i sent 04sleeper a PM as i trust his knowledge (just sent him a PM) but i also want to get some more opinions on this as im so frustrated and all i want is a good running car. heres the situation..
after installing the new motor, 3.4 whipple, fuel system and so on she got tuned by MPH (Tim Barth) this past december. i basically drove her straight home and into the garage after the tune.
i pulled her out a couple times so far this year when the weather was decent out and just kind of drove her around, nothing crazy and seemed to drive fine other than a very occasional 'buck'. last week i took her out and actually made several successful pulls (2nd-4th) without any issues and she pulled like a train. several days had past and i took her down to the exhaust shop to get some work done. started it up, idled how it always has and began driving. i attempted to get on it a couple times but as soon as i gave her half throttle she bucked/gargled and i let off. i was like ok guess she doesnt like the cooler weather (48ish). got to the exhaust shop where it sat for approx 5 minutes before being re-started. on start up it cranked longer than normal and when it started it idled like shit. the second you hit the gas it died. it took several minutes and attempts until i got it started and acting 'normal'.
the following day i picked the car up. started up fine and drove home fine, all normal driving. i let it sit for a couple hours and when i went to restart it, it did the same long crank, idle like shit. as soon you hit the gas to keep it running its popping and gargling like crazy. after it died a couple times it began idling fine. i backed it out of my garage, shut it off and washed it. after the wash it started it up, started fine and idled fine, then began making my way to my buddies shop. after about 10 minutes of driving i stopped at a stop light and she started idle surging and i was damn near dead in the water as i drover through the intersection but i kept on the throttle to keep it running. the entire time i was on the throttle it ran like shit, bucking and popping. eventually it straightned out and ran ok again. i attempted to give it full throttle and after a second of pulling it felt like it hit a brick wall, then it would catch for a second and hit a brick wall again.
Today, i disconnected the battery, let it sit for awhile and still the same results. its hard to crank over and get started. idled like crapand wanted to die, then it straightend itself out. then it started idle surging and died...and repeat.
cliff notes:
-i did not change a thing since the tune other than installing a fuel cooler on the return side.
-did a smoke test today and noticed a smaller leak, but a leak coming from inbetween the superchager and the inlet. not sure if its where the inlet meets the charger or from underneath the charger and if this 'leak' is enough to cause this problem.
-tuner told me the other day it could be fuel deposition due to me running the Aeromotive eliminator pump. (i do run a fuel cooler, but it was tuned without). dont know how it could be this especially on cold starts to.
-i felt the pump after driving the other day and a newborn baby could put its hand on it, it was barely that warm
-im running E85
-no engine light on
ideas :??:
