need help with ls1

[99ta]

ok, heres the deal. having an issue with my TA. couple months ago was spraying the car and when I went to hit third gear the car fell on its face real bad. put it in neutral and it died. will start right back up but runs very very rough, idles at about 200. and barely any throttle response. right after it happened I found the pcv valve tube had came off the back of the tb and there was a hole in it. replaced tube and still same thing. changed all the plugs and they all looked fine. no engine light. first, anyone have any ideas? second, anyone have a computer I can hook it up to to see whats going on? thanks

Eric,

 

I have had a bit a rough time this month. I need a couple hours here at home to tie up some loose ends. If you want me to pm me your address I will see about coming down with my laptop and hp to see if we find out what is going. We can try turning misfires on with the scanner and see what cylinder is causing the problem.

Is the fuel soleniod stuck open by chance? Assuming you still have the kit on the car. Do have a fuel pressure gauge to check pressure?

Brian, sending you a PM.

 

sam, the kit is still on the car. never thought of that, but it is not activated. and no I don't have fp gauge to check it with.

If the soleniod is stuck open the kit wont have to be activated to still work. Once the fuel gets to the noid and its stuck open it will flow right past the noid into the fogger then into the intake.

how do I check that? have to unhook it?

Yup, just pull the line off after the noid. You'll prabably want to plug the line going to the nozzle so not to create a vacuum leak (depends on where it is), I'd just tape it up. You'll only have to key up the car to see if fuel leaks out of the noid.

[Sam1647545489]

Take the line off that goes to the fogger. Turn the key on and see if gas comes out.

O2 sensor? My car did something similar after I started spraying but I also had the check engine light on...

no gas comes out.

check the plugs

[1slow-z]

check the plugs

 

He said they are new

[Guest Removed]

He said they are new

a few could be cracked... or even burnt after the heavy doses of spray!

 

edit, maybe you should read the thread..the o2's are new..he never mentioned plugs

[V8 Beast]

My o2's were 5 months old when they went bad. Since they were new I checked everything else but them. Then after 2 weeks of bs the check engine light finally popped on and it was an o2 code. We thought is was everything from a vacuum leak, to bad springs, to cracked plugs. The car was surging like crazy, stalling, and felt very choppy. If thats what yours is doing you may want to borrow someones o2's just too rule it out.

[99ta]

Rob, I changed all the plugs. they all looked fine (I did mention that in the original post).

 

Brian, I guess I will check them..... Looking for anything right now. have a ms3 waiting to go in.

[V8 Beast]

I'm hoping its something like spark plug wires, or o2's... hopefully its nothing more serious. Keep us updated.

[99ta]

update: change the TPS, nothing. Got my hands on code reader. have pending codes po171 and po174. lean in both banks. is there a way to check the 02's before replacing them since they are so new. have looked for vacum leaks and sprayed starting fliud around to look for leaks. any ideas? would love to find someone with a comp to see what is going on....
