Exhaust changes causes problems

[rogerzr1]

I talked withy Jeff and looks like I will hopefully get him to look at the car while he is in Birmingham. As I told him, I have never worked on cars before. Looks like I picked a good vehicle to start with.

Hopefully I will have some good news after next weekend.

I appreciate everyones help!!!

Seems like everyone on the Registry is willing to help a brother of the beast out.

I am hoping soon to not be sooooo much trouble.

I am sad to say I don't know. They are the Ac Delco plugs. The mechanic that put the in said they were the correct ones for the car, but right now that doesn't mean much to me.

Hope to find some answers next Friday.

gm recommends .035'' for 90-92,and .050'' for 93-95...generally speaking,a smaller gap will give you easier starting while a wider gap is better for high speed...i would start with .035'',and go from there,keeping in mind that too wide a gap can cause misfiring,,,mine are set at .040''

Spark plugs are a cheap place to start.

I had a bad spark plug on the Z loosing pressure.
I started with the cheapest parts spark plugs.

And make sure you gap then .032- .035 i don't care what GM reccommands.

One quick thing to look at - The vacuum hoses on the back of the plennum and on the fuel pressure regulator. If you had a slight back fire - they may have come off. Might contribute to your fuel issue.

Good Luck

Issue resolved!!!!!

ALL HAIL JEFFVETTE.

I went to Birmingham to the vette gathering. Jeff was there helping Fred with his Zo6 race car and for the vette get together. After a long day driving the Zo6 on the track, Jeff took a couple of hours to help me with my car(I know he was tired). We were at Chris's house. (aka. Corvette95-Talk about a garage and car room. I hope Chris will post some pics of his garage, paint shop, basement room, and attick. Amazing). He was nice enough to allow us the use of his great garage. Anyway, long story short, problem turned out to be coil packs. Once again Jeff had anticipated this and brought the materials needed.

I have had the car since August 2007. Last night on my way home is the first time the car drove like it was supposed to drive. Man what a feeling!!!

I took a number of photos at the race track where Fred Turner and Jeff were taking turns in the zo6. I will post some when I figure out how to do it.

Again let me thank everyone for their input and help.

Jeff you are the man!!!!!
