Swapping your ECU is a good idea, as the O2 sensor you swapped isnt causing the problem, changing out the ECU would be worth the time / trouble it takes

Aside from that, the fuel delivery system is probably what we need to start looking at next?
Also, what about your engine temp sensor?

hmm. I dont if or when the engine temp sensor was changed and I will see if I can find another ecu to swap. I just think its weird how this problem just came out of nowhere. its starting to become very frustrating.

I would imagine, I have had a couple really annoying things happen that took a while to run down, don't give up

Bad fume smells?
Do they change over the time when the car is warming up?
Or are they constant?

so the ecu is on its way but ive notice things are getting worse. when im driving and i go to shift, as soon as i let off the gas the car either will stay at the same rps or give itself gas for a split second. I oiled the springs on the tb and everything looked to be working properly.
Also I dont know if this really matters but when i pulled the mainfold off a couple days ago I noticed that there was a slight oil buildup.

Interesting, besides your ECU and TPS, I am not sure what else.
If your ECU is wacked, get that swapped out and we can go from there.
If you have access to a spare TPS, that would be worth checking out.

could one of my injectors be bad and the other three try to be compensating for the faulty one.

There would be a CEL and OBD code for an injector problem normally. However, stranger things could happen

Do you have spares to test with?

I beleive you can test your TSP with an ohm meter... just unplug and check the resistance as you smoothly move the throttle. i'm not sure for the exact proceedure, but i remember seeing it here somewhere

i replaced the tsp and i swapped the ecu yest and to no avail. cel came right on while idling. I took it down to a mechanic to get his opinion and he said its my fuel pressure regulator. any thoughts?

roundel318 · « **Reply #56 on:** December 26, 2008, 05:14:39 PM »

Good to know about the TPS and ECU, FPR could be culprit, but what about your injectors?
How does it idle other than the CEL?
Does it pull well?

nofear3544 · « **Reply #57 on:** December 27, 2008, 12:16:04 PM »

it pulls like a champ and the it idles fine even if the cel comes on, it remains perfect. it only rides high when its cold. the thing thats starting to confuse me is when im on the highway it gives itself gas. ill let of the pedal and it will continue to give itself gas for a split second then the car will slow down. the same is when i press the clutch, u can hear and see it rev slightly by itself. I ordered a fpr so i should have it installed by next weekend.

Also I unplugged the O2 and drove it for about 100 miles to see if there was a difference and it feels the same.

roundel318 · « **Reply #58 on:** December 27, 2008, 04:37:13 PM »

Interesting that you unplugg the O2 and its the same, did you get the same CEL 1222 with the O2 unplugged?
Is there a way to test the wiring of the TPS?
I have forgotten at this point, you did a visual on your TB and it opens and closes and is at the right places it should be, like being closed when throttle is at idle and open perfectly (not at an angle) when at WOT??
I presume this is how it should be...?

nofear3544 · « **Reply #59 on:** December 30, 2008, 07:19:43 PM »

yes the car is pulling the same code although now the cel is on all the time.

I dont know if this is relative to my situation but i have noticed that sometimes while raining if I go through a puddle and splash the bottom of the passengers side of the car, it seems like everything shorts out and the car almost stalls. All my lights pop up briefly on the dash (the cel,oil, brakes, etc) and then dissapear and the car is fine. I almost think that this problem is due to a broken wire and may have something to due with my 1222 code.

Also after startup when I take off and start driving, I will get a bell (the same bell for the door being ajar) but it will only ring once and will not sound again during the duration of trip.
