Re: Make slowboy not so slow

Well I risked the 4 hour drive back up to the cities, and the car made it. Not without a couple problems though. First, I think my valve cover is leaking really bad, it started losing oil somewhere on the timing belt side, so I have an oily engine bay on that side now. I had to put in a quart half-way up here. It may just be a gasket issue, or the valve cover may be warped too since it didn't fit quite right on the new motor, rocked a little back and forth without screws.

Also, I'm having a super weird problem with fuel, and it seems ECU related. Under mild acceleration or < 5 lbs boost the car operates great. However, it starts to act up big time when it stays constant throttle for more than 10 seconds or so, then something triggers and it runs like crap. It gets really bogged down it seems like, and shudders a lot, and I thought something in the drivetrain was loose, then noticed my A/F gauge was stuck at lean, not blinking back and forth like usual. Giving more gas and trying to accelerate doesn't fix the problem, it's stuck in this mode. However, putting it into neutral for a few seconds, the light blinks to rich for a second like usual, then i can shift back into gear and cruise normally. A few seconds later, it suddenly triggers back to crap mode. However, if I constantly fluctuate the throttle a few percent, it doesn't get into this mode. Any ideas?????
