So i let my sister drive my car to the store 3 days ago (first mistake) and as we were leaving the store she put the car in Drive instead of reverse and drove over a curb with a 2 foot drop. The car slammed right where the oil pan is and it was banged up pretty bad, and the exhaust pipe was roughed up also. After the car hit the curb the engine sputtered for 1-2 sec and died.

After that i have a choppy idle at about 800 rpm and occasionally it will just die. I'm getting terrible gas mileage and i have complete power loss. Its almost like driving a totally different car.

Today i drove it in the rain and barely tapping the gas it will jump up to about 2500 rpm and accelerate pretty slowly. Now before getting to 2500 rpms in first would spin the hell out of the tires in the rain. So after that i stopped and floored it, tires didn't even slip it just accelerated incredibly slow...

The car sounds choppy at all RPMS and the tach jumps a couple of hundred rpms every second mainly when accelerating, not so much at a steady rpm. But there is a definate sound you can hear...

On top of all this there is no SES light.... There appears to be no damage under the car other than the scrapped up oil pan and pipe... what could have happened please help

 

Exhaust choked off due to smashed pipe? Catalytic converter fubar? Fuel line smashed? Need to get the car up on the lift to check things over. And check the ignition wires, etc, to make sure something didn't get jarred loose.

 

Exhaust pipe is only scraped up its not really dented in at all, i have no cat... fuel line i dont know about ill have to check if it were ignition wires wouldn't that set off the ses light


This is on the 88 iroc btw

 

Checked over everything and everything seems intact... I have NO Clue what the problem could be

 

Well looks like i've narrowed it down to one of the cylinders not firing once i find the damn bits to take off the cover of the distributor ill be able to check...
