i have a few problems...

#1. one of my injectors were leaking so i replaced the studs, nuts, and the spacers, and the injector o-rings... the spacers were too think for some reason and my injectors didnt sit down completely so i grinded them down and got the injectors as close as possible, but any ways.... the problem is that when i start my car up my a/f gauge says its running rich, after 1-2 minutes it goes to lean, then after gets to opperating temp it goes back to rich. but when i start driving, after a few miles the gauge will then peg lean and then stay there.

#2. my cel comes on as soon as i start my car up but every time i try jumping it the cel turns off and wont blink, once i pull the wire out of the connector it turns right back on... the car drives fine as far as i can tell besides problem #1 and then problem #3 and #4 (listed below) (( NOW FIXED ))

#3. the car hauls through every gear till about 4k rpm where it then kinda seems like its struggling to gain speed. (( NOW FIXED ))

#4 after the car gets to operating temp, at idle the rpms bounce from 1200-1500rpms... idk if its because of my cams but its just weird because i didnt notice it doing that before. but when i drive and come to a stop it sits at 2k rpm for a couple of seconds where it then slowly drops to 1200 and then bounces between that and 1500 rpm.


now i already know people are going to ask whats done to it to help solve some problems.... here it is, it was turboed (very short period of time, turbo mani blew apart and dont have money to have remade right now), so now its just a dc header, full 2.5" exhaust right now... basically its a fully built engine... if any one needs to know a specific detail just let me know... also i recently replaced my tps (wasnt brand new but was tested to work perfectly), new o2 sensor, external coil for dizzy, some what new wires, and i just cleaned the iacv completely only 75 miles ago do to idle bouncing from 1200-2700 rpms...

for the fuel rail, u might need to use non oem shorter bolt to tighten the fuel rail which is what i use. i had the same problem as u did. fuel rail was loose. and also check your fuel injectors if every one of them is working fine. u said the car was turbo before, then ecu must have been tuned and remap to accomodate the bigger injectors and once u took the turbo parts off and going n/a did u get the ecu remap and retuned again ?

idle problem sounds like a vacumm leak. Did you change out the throtle body at all. Im sure you had to do modifications to the vacumm system with the turbo double check to make sure everything is correct. If push comes to shove spray carb cleaner over the vacumm system slowly if you have a vacumm leak when you spray the cleaner on the leak your idle will temporarly be normal then back to the way it was.
Did you have the ecu tuned. If its still tuned for the turbo it could be causing a lot of these problems.

well i fixed problems 2 and 3 today, i rechecked everything and found that my number 2 cylinder spark plug was going bad, it was only randomly misfiring right now and when got to higher rpms it then would misfire like crazy, so i changed it and now the car runs a little better, gets up to speed quicker and no more cel... but i still have problems 1 and 4

If you are getting random misfire, along with a bouncing RPM gauge, your ICM is about to take a **** and die.
