Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!
If you have any problems with the registration process or your account login, please contact us!
Thoroughly disgusted at the moment.. ***** is gonna sit for awhile...
Love the new avatar tho!
I was always taught as a rule of thumb to replace the gaskets if you have them off for some reason or not... Your a pro at taking that intake off now, get to work! If you were closer I would have love to lend a hand.
I had the same problem recently,turned out my TB gasket was ripped at the bottom by one of the bolt holes..New gasket and all is well..might be worth a shot..also I was getting the same code,pointing towards the MAF..
Question: Voltages to the Throttle Position Sensor? Not trying to be a smart ass Larry but, did you get the TPS installed correctly? Reason for asking is, I installed a TPS wrong. It gave the computer fits. The computer received signal voltage stating the throttle blades where full throttle at all times. This caused a pig-rich run condition. Once warm, the ole monster 305 would NOT start. Needless to say, I was taking cool down breaks quite often before I grabbed a BFH and really broke something.
Just throwing this out there Bro.

some experience here! Hopefully its a easy fix larry!
Thanks for the input guys... TPS was never removed from TB.. Coolant temp was never unplugged(but will check)(you're talking the sensor by cyl 1).. I did check the TB gasket and it looked fine.. Going to try MAF Cleaner later, if it keeps kicking out the MAF code, then off comes the intake again... Anyone have a link to a PCM diagram showing what pins are for what? I used to have a link but can't find it.. But going to let it set for awhile.. Too fricken pissed at the moment..
Edit: Checked coolant sensor, plugged in.. Rechecked all wiring, everything looks normal.. Leaning towards gaskets, cause honestly, I didn't check them as well as I should of and this is probably the 3rd time I've had the intake off and back on.. Have a fresh set of eyes stopping in a bit.. If Mike doesn't see anything unusual than off comes the intake...

if its tuned correctly you can just unplug the maf and it should run fine. gaskets would normally cause a high idle and a lean condition.
if you can check the coolant temp with a scanner. usually when they fail/damage they goto -40 degrees which will dump a ton of fuel.
but....
now on the other hand. that code pushes the pcm into speed density which is probably the issue. its probably dumping fuel due to the tune.
and a bad maf or unmetered air can cause that issue

I'll try unplugging the MAF.. I have no way to check coolant temp..

If the coolant temp sensor was bad wouldn't that kick the fans on? Or is that only if it was un plugged?

I'm leaning towards a MAF problem. Intake leaks usually cause a lean condition or a high idle.
But if Mikes MAF doesn't work just pull the intake off. It doesn't take more than 20min. New gaskets are cheap also.
Swapped out MAFs and still the same issue.. I have new gaskets(Thanks Mike!) and will swap em out next week sometime.. I just have to walk away from it for a couple days...
