Need some HELP in Ann Arbor!!

[Haans249]

Hello Everyone!
My first real post here, woohooo! Anyways...
I just did a bunch of installs on my car during the two weeks break over christmas...took it to a performance shop in Dearborn, had it dynoed at 441 and 400 trq to the wheels! Quite happy with that! There is a problem though...and the shop couldn't tune the problem....

My car wants to stall everytime I come to a stop light, stop sign or basically anytime I take my foot off the gas and push in the clutch!!!!!!

I have been going through trying to remedy the problem and have replaced the IAV valve, and the O2's to vette rears (240 in total) with no such luck.

Next is to replace my intake port seals on my FAST 90, and see if that helps.

I don't think it will, as I think its something tuning related.

BIG QUESTION = Does anyone have HPtuners or EFILive in the area (detroit is close enough for me) that we can use to scan a run on my car, and see what the tune is like? I have a 2001 WS6.

Hope to hear back from someone!

Well sorry to hear of your misfortune but welcome to the site. I have HPT but its only for 98s and 02s I'll let you know if I find anyone with 01.

[Haans249]

Thanks a lot!! Hope you find someone, as I'm sure its something with the tune....I'm going to mess around some more with my idle set screw and see if giving the engine some more air will help, but I've already done it haha.

Thanks!

Did you drill a hole in the throttle body? It may not be getting enough air at idle.

[Haans249]

Well, there is a way you can do that without having to actually drill the plate. One such way is to open your plate till your read 2% open or so, maybe 3%, and then turn the car off (car doesn't have to be runnign when doing this, only ignition in ON position). Unplug the TPS, and then turn the key to ON again, and let it sit for a min or so. Then turn back off, and plug back in your TPS, and it should read back to 0%. This is the same as drilling, but works better in my opinion. I've done this already, and it still boggs when coming to a stop light. I actually just added another 2% or so ,and am going to see if that helps any. Kinda scary when you start your car and it idles at 2K rpms for a min before it comes down haha.

anyways, will keep you posted!

That's weird. my car does the exact same thing on occassion. sometimes when i come to a stop...my car will literally go to 0 rpm then zing back up to like 2grand then down and up a few times till it settles down. other times when i come to a stop/put in clutch my car will stay idling at like 1500-2000 rpm. i think it has something to do with my tune and cam. my car has never...well a few times....but usually stays running. it just idles all over the map at times. also if i've been cruisin down the express way for a while, when i get off my car will continue to idle at like 2g for a while.? so i have no clue lol....just my $0.02.... so you're not alone with the messed up idle...what did you do over break???? cam 'n' stuff??? what else??? 441 is a pretty good number...im at 390 with heads/cam and bolt ons

[Haans249]

Yea, that sounds exactly like the problem I'm having. Just curious, where did you get it tuned....lets see if it was the same place, then we know their tuning blows....but here is the list of MODS

Cam = 228/236 .612/.590 114+2 LSA XER
Volant CAI
SLP MAF 85mm
FAST 90/90 intake/tb
SVO 42# injectors
ARE Stage 3 heads (.327 cfm at .600 lift) 61cc chamber yielding ~11.1:1 compression, 2.055 int/ 1.60 exh (cam cleared with no flycutting)
PP Gold Dual spring kit good to .650 lift
Camp Cams 7.275" Pr
Morel Lifters
Edelbrock Stepped 1 3/4 to 1 7/8 headers w/ 3.5in slip-on merge collectors and ORY 3" back to a 80 series slowmaster with 4 in slashcut tips
Powerbond 25% UD pulley

I believe thats everything, pulled 441 hp at 6300 rpms and 400 trq from 4500-5500rpms.

Thing pulls like a train, yet idles like my grandpa's old regal... =P

Just curious, did you remap your MAF table with all the mods that you did? I'm hearing that you have to remap it so its calibrated properly and maybe the cause of our problem...

Regards!

well the first time my car was tuned it was done at A.P.E. by the previous owner... i forget his last name. first name is kirk though. then the new owner of A.P.E. ran that place to the ground and they are outta business. when i put my heads on....(patriot heads) i had it dyno'd and tuned at Wheel 2 Wheel in madison heights. The same guy Kirk tuned it there lol. because after he sold A.P.E. he started to work for Wheel2Wheel. anyways. he did a great tune on my car. it's only some times that my car dues this. i don't know what all he did in terms of a tune. all i know is he sat in my car for like 3 hours and did maybe 7 pulls till he made my Air Fuel ratio look like a dead persons heart rate... FLAT. so i have faith in him. where did you get your car done at?

I don't have a tuner, but I have a MACTOOLS OBDI/OBDII Scanner that is capable of monitoring and recording all engine stats in realtime. It even graphs them and I have the software, a laptop, and the cables to hook it up to any GM or Ford vehicle 1986 and up. If you want to get together, let me know. It would have to be on the weekend, because I still have school and stuff going on during the week. I live in Adrian, so we might have to meet halfway or something. I'm up for it if you are! We paid over $1,000.00 for the damn thing and I haven't used it more than a handful of times yet. It works pretty damn good too. If your interested, leave a message here or email me at saxman06@comcast.net I hope you can get it fixed! I noticed that my moms cars idle was really low after we had the battery replaced, and it turned out that the code just needed to be cleared. Hopefully your fix is something that simple!

[JoeliusZ28]

i doubt this is it, but in my car's computer there is a "cruise idle" setting or something like that, that dictates the engine idle speed when you are moving and have the clutch pushed in and no foot on the gas. My car's stock setting is 1500 rpm, and its kinda annoying cause its too high. its possible the tune you have set that setting lower, but too low.

[93formulalt1]

Yeah- That's it. In Mom's Aurora, we swapped the battery, and it reset the PCM's RAM. The idle setting was lost, and the PCM trouble code had to be cleared before it would reset the idle on it's own. That probably isn't your problem, though. I can still run a diagnostic run on your car to see whats going on with it, though.

[SS4Matt]

I'm guessing it has something to do with the tune.......when kirk tuned mine...he made everything perfect and he was like "anything else you want me to mess with while im here?" i told him my idle was weird when i came a stop sometimes...he lowered my idle like 250 rpm or something...but it didn't help my problem?....however..my car doesn't stall like yours?...unless my car is still cold. (like if i run over to my friends house really quick a few streets down and i go to back into his driveway...sometimes it'll stall?) other than that...it doesn't die alltogether..just it'll go to zero RPM and then shoot back up to 2,000. it's weird. it has to do with the cam im sure.

wow this is my 400th post!!!!

[Haans249]

Hey SS4Matt, what cam do you have in there?

[Haans249]

06camarodude,
When do you think you'll be able to meet up? How far away is Saline from you? My parents live in Saline. Or maybe we can meet somewhere closer to you as well. Is your software able to view the tune that was done on my car? Like all those parameters that you were talking about the cruise idle and all? Because that sounds like my exact problem. It'll stay up at 2,000 rpms while cruising until I come to a complete stop, once at a complete stop, it'll go back to regular idle.
Also, since opening my plate more, when I first start my car it'll idle at like 2K rpms until it warms up when it comes back down to idle at like 980.
Thanks for pointing this cruise idle out JoeliusZ28!

Best Regards,
Adrian

Let me know what you want to do. I have a Dr. appointment in Saline this Thursday @ 4pm, so if you want to meet up after that, I am sure I won't have any problem with it. PM me an address and phone number and I'll see what I can do.
