Hey, guys.

My problem is my CEL come on along with the hesitation at all RPMs and at idle when my car has warmed up.

I start it up, let it idle for 10 minutes. It idles perfect and runs perfect for the first 10 min or so.

Than my CEL comes on and it studders.

Also, lets say I am in third gear.

I step on the gas, it boost builds normally (almost faster then when it ran fine and the BOV is louder too), but my RPM climbs slllowly, and I am not increasing in speed compared to when it runs fine.

How can my boost build, when I am barely increasing in RPM and speed??

What causes the CEL to come on at a certain temperature?

Please do say it can be anything, because only a few things will cause my car to run like **** when it is warmed up.

I changed plugs and wires. I changed MAS, and I changed ECU.

Nothing helped it.

Thanks in advance.

 

double posts? i swear i just read this.......dont think the mods like that

 

How on earth do you expect someone to tell you the cause when you haven't had the code pulled? That should be the first thing you do, get the code pulled. AutoZone will diagnose for free if you have one in your area. I will hazard a guess it's a P0300 though, so do a search for that to see if you're experiencing the same symptoms.

 

I got the codes pulled.

9 of them.

MAF
Coolant
front o2
IAT
CAS
Coil 1-6
coil 2-5
egr
vss

Take it to the dealer.

 

EDIT: maybe some kind of ECU ground/harness problem?

 

With all those codes, it sounds like a bulkhead connector problem.. or a problem with the wiring harness to the ECU..

 

Can you tell me how I can check the ECU bulkhead harneses?

Thanks,
Jon

 

dealership.huh?

is that the same response you want someone to give you?
