Pontiac Problems? Ask a Mechanic for Answers ASAP
Does it start running bad? or just instantly dies? like the key was turned off
OK. Do you have any DTCs? I assume that your 0135 was remedied with the o2 sensor replacement?
Ok. Im at a loss at the moment. I am going to throw this question someone elses direction. I'm sure it's something that someone here has seen before and can tell you what's up. If I think of something I'll let you know.
Hello my name is ***** ***** I can help.
I have seen the main wire harness rubbed through causing a Shorting out of some wires.
This normally happens at the driver side front just below the air filter box. The wire harness is rubbing at the trans housing or the A/C lines/dryer
Let me know if this helps
It only does it when in drive. Can you hold the brake and give it gas to make it stall?
If so try having some one move the wires than see if you can stop it from stalling.
Do you have a scan tool?
If so does it read live data?
Have you also checked the wire harness that is on the right of the engine? I have found some wires damaged there.
The under hood bussed electrical center wiring harness.
Can you tell if the Engine control module see the trans going into drive?
Is it cutting out or is it like a rev limiter?
Do you know how to post a video ether here or YouTube?
I would like to see what it is doing.
All so can you scroll through the data list and video it when it is cutting out?
Yes that is normal one is a MAP other is a BARO sensor
With your scan tool are you getting any vehicle speed reading or is your speedometer jumping? When sitting still
The egr valve should only open when moving
That is a normal reading for the ABS. Code C0240 set because the is a PCM code set.
The PCM detects a malfunction and then causes TCS shut down until the malfunction has been corrected.
I wanted to know if the trans output sensor is showing any speed.
What codes do you have set in the PCM?
Are they EGR codes because you disconnected it?
Was this problem happening before you replaced all the parts you listed?
Can you scan tool read the VIN# ***** the PCM? Does the PCM/ECM look like it was replaced?
Plug everything back in. Try unplugging MAF sensor
Have you test drove the car with the EGR unplugged?
With it plugged back in. What does your scan tool show what the ECM is requesting?
When you look at live data there should be ECM comannd EGR % opening and actual % opening.
Ok just keep me updated
So with the EGR vale plugged in you can see the actual opening on the scan tool?
What is the reading?
Did you drive it with the EGR valve unplugged?
I just need to know have you ever taken the car on the road?
Have you tried running it with the exhaust converter unhooked?
I think you my have a restricted converter.
You could take the 02 sensor out and drive it see if it helps.
I know I'm trying my best to help.
Did you do a crankshaft position variation relearn?
The rpm you are looking at is on the scan tool?
See what the scan tool shows.
The engine should not stall even if the EGR is fully open at the RPM you are running. If you let off and it is still at 100% than it will stall.
We are just over looking something.
I'm sorry for the delay. I can't think of anything to help with out driving it.
Sorry I will opt out.
