So I recently had the engine rebuild, about 2500 miles ago. It has mostly been running great since then but now I have been having some strange starting issued. I was having rough cold starts and I had Scanwest replace the fuel filter as well as the pressure regulator, which fixed those problems. Now I am having really rough starts on a warm engine. The last time I started it I had to give it gas as it was kind of choking and not wanting to really get going. Any thoughts? I cannot keep spending money as Scanwest and would love to be able to fix this myself.

Not sure on the fuel pump, DI is good as I have four and put that one in not too long ago. What is the CPS? (crankshaft position sensor?) Will check out but I don't think it was messed with.

Ok so I have not gotten around to checking the CPS yet, but the car has thrown p0133 twice now, and I turned it off and have not seen it for a while now... Could they be linked or is it two different problems?

Replaced the DIC, and the CPS(got rid of the code). Also cleaned the TB and replaced vac lines. Still having the same warn rough start issue. Starts great when it is cold and when it is hot, the only time it starts rough is when I drive it and let it sit for 20min to an hour then I need to give it gas to get it going... I hear the fuel pump prime, and the FPR was recently replaces because fuel pressure was dropping when the engine was turned off... Could this be the fuel pump check valve? Or maybe some electrical controller?

Anyone? I just put new plugs in and still having the starting issue. I am thinking it is time to get to that fuel pump, as I cannot think of anything else it might be...

I recently took the TB apart and cleaned it, as well as replacing the vac lines. Are you thinking it could be the electronics? I hear those wires in there can get fried, I might have some time tomorrow to take it apart and take a look at the wires...

If you suspect the fuel pump check valve, then turn the key to ACC but don't go all the way to engage the starter, do that a couple of times, then try to start.

WIS tells me that P0133 is a slow responding O2 sensor #1.

No i have not had any luck. Still having a warm start problem. I have replaced the vac lines, sparkplugs, dic, TB, cps, front o2, fueses, and I recently took it to Scanwest and they replaced the FPR as they saw a drop in fuel pressure at shut-off on their tech-two. The strange thing is that I figured I would just keep driving it and wait for it to get worse. Well it has not gotten worse or better, I am pretty much at a loss as to what the problem is... Could be fuel injectors? Maybe something to do with the fuel pump, but I just don't see that being the problem only on a warm start...

Ok so I had the car into the shop. They fiddled with it for about a week, and finally decided they think it is the computer. My 99 viggen is part of a TSB where the computer had rubber washers that corroded. Since I recently rebuilt the engine and have not fixed a lot of other stuff I want to tune it and get it up to 280-300. I did not have them replace the computer as it would have been about $350-400, and I figured that will be something I can take care of when I tune it. What do you guys think? I have not found anything about this TSB, so I really don't know, I however do trust the shop as they are standup guys.

Here is the TSB:

MI No. 248-2261 ed.2
PI No.

Date: September 2000

Recall 724: Replacing engine control module (ECM)

Background

The Trionic T7 engine control modules manufactured before December 6, 1999 have rubber supports for the circuit board that are faulty. These supports contain substances that can accelerate oxidation, which in turn can lead to open circuits on the circuit board. This can produce symptoms such as starting problems and the engine running unevenly. The CHECK ENGINE lamp may illuminate and the car may go into limp-home mode.

If Recall 719 has already been performed, please see this bulletin for additional work that must be performed. If Recall 719 has not yet been performed, please see MI 291-2217 edition 3 for complete details on required work.
