Ive had this car for a year or so and been trying to solve this myserty myself but to no avail..
When i open the throttle more than 1/2 way it has a miss starting about 2800 rpms and gets worse as the rpms climb. As the engine warms up the misses get worse, to where it will barely go above 5200 rpms. it fells like an ignition problem, like an intermittant plug misfire. i replced all 8 plugs and wires. No change. Then i replaced both coil packs. Still no change. Cleaned MAF and that didnt help. Had a GOOD but used MAF that i put on the car and the problem still persisted. Has a new fuel pump and pressure is right on. Does not have Cats so no O2 sensors. And the topper is NO CODES... So im at a loss...scarily close to tears.
Please baby jesus... a lil help here!!
