I have a miss or something that makes my car jump when accelorating and crusing,it also makes my tac drag or jump when Im hard on the gas...I have new plugs new cap and rotor ,wires,ignition modual and new fuel filter... Idols great just have problems when under any foot to pedal power ...Ideas anyone PLEASE..
check your TPS. Takes a few mins with a volt meter and is a cheap/easy repair. Mine went out last year and let to all kinds of gremlins. Surging/dying/bad idle, then sometimes it was great..........
Tachometer is exclusively wired to the coil. If you have driveability issues combined with a funky tach, chances are near 100% that something is wrong with the coil.
Update I went out lastnight with a bottle of water and sprayed my plug wires and one was blue arking almost all the way to the plug I reordered new wires today.....Do you think this is my problem with miss and tac issues??????
