Hey guys, so I have a sort of interesting problem going on with my 88 325i. It ran and drove pretty fine before, but I recently crashed into a deer going about 50.. Bent things in up front pretty well. I've replaced the engine fan and clutch, and straightened out the radiator fins so it works fine. Disconnected the belt to the A/C.
The car hardly runs with the airflow sensor plugged in, it fouls plugs and covers them with a thick black soot. It surges at idle but I'm sure there's not an intake vac leak. Smells rich too. dives like ****. If I unplug the airflow sensor it will idle better, and accelerate fine if I give it 1/4-3/4 throttle, then if I stomp the pedal it cuts out, and spits and sputters. It will also jerk if I'm just barely giving it gas in a high gear to maintain speed. This all leads me to think it's the TPS, but I don't see how an accident could have changed how it works.
I should also note that the deer bent the actual engine fan pulley, so that it was rubbing the gear which the crank sensor uses. I corrected for this by spacing the fan outwards, since it was hardly angled. It barely, and I mean BARELY touches that gear now, and the car runs no different.
I've already replaced the crank sensor, and tried a couple different airflow sensors to no avail.
Any help would be appreciated, I've been at this for a couple days now. Anything else the deer could have damaged?
