    318i e36 rough start

    Hi guys! My e36 has the following problem: when you start it, the car seems to cough, won't go, you need to wait until engine gets hot a little, and it will go but it feels very underpowered in low rpm, and in higher rpm seems like a huge different car... its not supposed to fast at all but its quite lazy anyways... any ideas why?

    A wild guess, you have a serious vacuum leak.

    Your question was moved to the model specific discussion area.

    Measure your crank sensor, should be close to 510 ohms.

    Use injector cleaner over the next 3 tanks of gas.
