the CEL went away when we put a new O2 in it, nothing changed when we put my dizzy on it. I put new ground straps on it yesterday and the tach came back. Now it just wants to fall on it's face while taking off. we tried a new fuel filter and it got a little better. it feels to me like it's not getting the right fuel. hooked up my ecu to datalog a little and all I saw was the TPS looked a little flaky but when we got out the voltmeter and checked it was fine. I gave him a spare throttle body with a good TPS on it for him to try. it's just got some gremlins we need to hunt down.
