1992 oldsmobile 98 touring sedan, S/C L67. ok,
the car has a rough idle and misses constantly. it usually runs fine for normal driving, but misses terribly on hard pulls when the engine is warmed up. sometimes it will be missing very bad while driving, so i will turn off the car, turn it right back on, and the miss becomes alot less apparent, but it gets worse again a few seconds later after driving a little more. other times, it just floods out, or it will not increase in rpms, like, i can be in park, push the pedal a tenth of the way down and get the rpms to about 3-4k, and then floor it and the rpms drop to 2k, and the motor sounds like its struggling, the coilpack also ticks really hard when this happens. when it is acting this way, it is undrivable, because it floods and kills constantly, or i cant get going faster than 15-20mph. other times while driving, i floor it and there will be a strong pull, then it stops accelerating, then pulls again, and stops again, over and over. it is temperature related, the hotter the engine gets, the worse the miss gets, and it has been getting worse and worse over time. any ideas or comments would be very appreciated, thanks.
