Mercedes c230 1998, P0170 and P0301 rough ideal/acceleration?
 

This car got front end damaged about one year ago, it was not very bad, but the frame was a little bit pushed back. Since the accident happened, the car was parked for a whole year without being started or derived. I just recently fixed the body damaged, but now I have a mechanical problem and my question is about it.

The car ideal roughly when it is cold, but when it gets warmer the ideal become normal. The other problem that the car doesn't accelerate normally, it takes longer time to reach high speeds. Also, the car barley reach 40 rpms, even though I press the gas all the way down.

I have already changed the spark plugs, but nothing changed. The car was running really good.

Any suggestions?

this MAY be the ECT( Engine Coolant Temperature) sensor.



code P0301 : inspect the wire to the number 1cylinder for damage. measure resistance


code P0170 : P0170 Fuel Trim Malfunction (Bank 1)


good luck
