Re: Exhaust changes causes problems
 

ok, just grasping at straws since the car isn't in front of me.

Wonder if they put the injectors in correctly, meaning they used the top indent for the c clip.

I would start looking at spark. This is when a scan tool is handy. Just makes it all the easier when you can see fuel trims, knock counts and 02 fluctuations.

Re: Exhaust changes causes problems
 

I just have ordered the Helms maual, no scan tool. Should I go ahead and get the fuel gauge and check that or does it not sound like a fuel issue?

Roger,if you have a digital camera take pictures.
Close up of what Jeff mentioned the injectors,unplug a primary and take a close up.

I would change the Wires.

Problem is I have never taken the plenum off. I had the other work done and can't afford ($) to take it back to the guy right now. I guess I could try a plenum removal.

Re: Exhaust changes causes problems
 

Plenum not hard after you've done it once. Actually, it's not hard the first time, but a little scary since you don't want to mess anything up.

Get your tools together, the Helms manual, and a WARM place to work and you're all set.

btw, where in Georgia are you?

roger, i think jeff has apicture guide on plenum removal, but not totally sure . I ampositive he could guide you through it . the process is alot easier than you might think . you just have to go slowly and make sure you remove all 4 electrical connectors that are under the plenum 2 from the front and 2-3 from the back 3 if one includes the map sensor . you dont have to seperate the throttle body from the plenum. it comes off in one big piece . but the decision to do it is up to you .is there anyone close that could help this nice guy out ?

Re: Exhaust changes causes problems
 

I live in Cartersville. I wanted to maybe watch plenum removal a couple of times before I tried, but looks like that won't be the case.

Its not really involoved, you can do it. Links here to help you out. Take your time, observe and go slowly.

Re: Exhaust changes causes problems
 

Ok guys, I checked the fuel presure. Here is what I found:

With key on(no engine on) - 46# about 20 minutes later 30#

With key on(no engine on and seconary fuse pulled) - 48# 20 minutes 36#

WIth the engine on - 44# at idle car off presure at 44# for 20 minutes

I don't know what any of this means.
Does any of it make sense?

Re: Exhaust changes causes problems
 

Roger,

Data indicates the problem is probably not with the fuel pumps.

Few questions:
1. Did you ever change the fuel filter?
2. Did you ever experience any of these symptoms, before installing the new exhaust system?
3. Have you pulled the stored codes?
4. Are you getting any warning lights on the display?
