tip in throttle lean/hesitation
So ive been driving my car all this week since i got it running and am having a problem with bad lean condition and hesitation/misfire when i just barely give it throttle. Mainly occurs at crusing speeds and leaving from a stop. Wideband with go 17-18:1 sometimes leaner and will clear up with more throttle. Car hesitates and sounds like a misfire but it could be popping from being so lean. Im ordering a Tweecer and hoping ill be able to clear it up. Ive tried to up the FP, its at 48 w/ vac line off, but cant go too far w/o sacrificing idle (72lb injectors & no chip). Seems like it gets worse the longer i drive it, coolant temp around 190* or so. TPS is at .98. TPS, coolant temp sensor, MAF are all new. 02's are not. What do you all think??
