I have been getting an occasional misfire approx. 1800-2200 rpms. I parked it 2 weeks ago and today decided to take her for a spin. I put 60 miles on with no problems. I then decided to go for a ride 20min away I got there and the misfire came back. After I got there I noticed my idle kept going up and down. I left to come home and made it 4 miles before it staled on the side of the road. It started and stalled 2x. Going by GMhightechperformance.com's article about diagnosing a bad opti. I have most all of the symptoms.
Can someone point me to a how-to for changing the damn thing or give me some options and ideas for a cheap source to repair this little issue.
Thanx in advance,
Chris
