That sucks man.

My next step would be a compression test and make sure everything is good there.

 

I am having the same issues right now but with no CEL

 

IM having the same thing happening to my 2000 has any one found a fix would cleaning the tb help at all

 

You know from my own personal experience, it sounds like you have a loose vacuum hose somewhere. This will cause some of the symptoms you've been explaining, although it might/ might not be related to the engine codes the car is throwing out.

I would suggest looking around your engine bay, particularly around the intake area for a vacuum hose that has slipped off. This would cause major hesitation, crappy idle, engine stalling out, etc. Just basing it off your experience.

 

After reading your thread again, Im almost positive you have a loose/ disconnected vacuum hose somewhere. Especially since you noticed the change was very gradual, and not immediate.

 

Just double checked the vaccuum lines. They're all on and not damaged. Checked connections coming from the intake manifold (2) and the few in the back going to the EGR looking valve thingy.

Are there any others? Any chance that the two boxes that the vaccuum hoses connect to are bad? What are those anyway? One is the little black cylinder that was originally on the top rear corner of the intake box, and the other is a big black peice that attaches to the crossmember.

 

My only other suggestion is to see if you can swap out your ECU with someone elses stock ECU and see if that might have a malfunction. As long as you guys are the same year/ model, I believe they should be mapped the same from the factory. That way you can narrow it down to something mechanical if the swap is unsuccesful.

 

Immobilizer? Unless it's different in the AP2, you can't just swap stock ECUs, or can you just use their key to bypass that?

 

No easy immobilizer bypass to swap a test PCM.

You ever get as fuel pressure check?

 

No, I need to swing by a repair shop for that. One of the local sponsors is close by but I've been busy at work with no time to go lately.
