Well, the car has decided to be a pain in my ass. As you (may or may not) know, my boost bypass valve was bad. FINALLY got through to Saleen and purchased a new one, it arrived earlier in the week. While replceing the bypass valve, I also replaced my belt. Even though it only had about 7k miles on it, it was starting to become a little stretched.
Since the replacement the car has been acting pretty odd. Symptoms are not as bad when at full operating tempature as they are when cold, but still exist.
On a normal takeoff, like neighborhood driving for example, the a/f jumps off the damn gauge. Goes up to around 17.5 according to the WBC gauge. No power, loud air sucking noise through the intake ( sounds like a smallblock with no air cleaner! ). Does this up to about 2200rpm, then runs fine. If I take off "spirited", the a/f doesn't jump as badly but still jumps to about 15.5 ~ 16. Although it does seem to run better. Running around 2500rpm in 2nd gear and floor it, a/f acts normal. Goes down to around 11. Power seems fine.
Two days ago, drove it for about 10 minutes, parked for about 15 minutes, got back in and drove. It didn't have the odd a/f readings or loss of power on takeoff. So I decided to romp on it from about a 20mph roll in 1st. It had plenty of power, got a little squirley getting in to 2nd, I stayed in it up to about 6000rpm, then shifted to 3rd and let it settle down. Looked at the dash and had a CEL. Got to where I was going and pulled the DTC and it was a P0170 ( fuel trim ). Damn... So I start poking around and trying things that I already had parts laying around to try. Replaced the fuel filter, pulled tht GT fuel pump and put the stock pump back in. Still same running symptoms. Nothing changed.
This morning I drove it around the neighborhood to do a little datalogging ( don't know why... it doesn't mean squat to me! ), parked for about 20 minutes, then headed to work. About 2 minutes in to the drive to work it threw a CEL. Pulled over and checked the DTCs, they were P0172 and P0175. Bank 1 and 2 too rich. Screwed up thing is, the WBC said it was lean. Was again around 17.5 when I pulled off from the stop, and was at 15ish when the CEL flashed up.
WTF?!?!
