Mime, if you wanna just throw parts at your car, feel free...but the main relay issue is NOT throttle dependent. After all, it is only shitty contacts.

I think mine may have been fuel related. A little dry gas and full tank of super and she's back to 100% . . . at least for now.

3. So.. ill be going from 1st shift at 3k (let go of gas) and when i go to give it gas in second. The car just falls on top of itself...has no power and ill hold the throttle down then all the sudden all power comes back and im off.
This problem will do it at any moment during acceleration but it MOSTLY does it after i left go of the gas to shift.

The car itself stays running but lunges me forwards due to the sudden loss in acceleration. Then the power is suddenly back and im off again.

Having almost identical problems, sorry to hyjack...

Does yours backfire at all when it falls on it's face? Mine backfires through the intake.... Could these be related symptoms? Still trying to figure mine out .... :(

Backfiring through the intake aka lean backfiring is either caused by the ignition timing being way off which really isnt possible on our cars since the timing isn't adjustable. Or by an extremely lean mixture causing preignition i.e the plugs are glowing hot and the fuel/air mix ignites and burns while the intake valve is still open. I would suspect you have a fuel problem. Fuel filter been changed recently? either way a pressure test and a volume test of the fuel system would tell you alot.

Same problem
happens in the morning and under full throttle conditions
I'm also only getting 200 miles out of a full tank
jim conforti chip
new fuel pump
new fuel filter
91 octane fuel and it has occurred with several tanks of gas so its not bad gas


I wanna buy a new engine ground strap
main relay
various vacuum lines
new cap,rotor, plug wires,spark plugs,coil

If that doesn't fix it.
try different injectors
new o2 sensor
