Car is trouble. No clue what to do anymore
I have quite a bit of money in just simple wear and tear items on the car like clutch, slave and master cyilinder , altinator, fuel filter oil filter all liquids, spark plugs, coil pack, throttle body(cheap one from a friends car that ran fine just was ripping it apart),starter. Fuel pump. But so now the car is stuck on engine power reduced mode and will not go above 3k rpms in and gear of the 5 and won't go above 30ish mph. I have been told computer maybe. But I'm just clueless and would like some sort of idea before o put any more money into it.
