1991 240 wagon. Recent motor replacement. Uses too much fuel and very rough idle. Have changed out following: ECT , ECM , MAF sensor and fuel pressure regulator. No improvement. Also I can detect gas odor in oil. What should I do next? Send replys to : [email protected] Thanks

Re: HELP! Fuel problem (samuel58)

I would check out you o2 sensor. Clear ot the system memory by disconnecting the battery and touch the neg cable to the battery positive for 3-5 sec. Then unplug the o2 sensor and see if it runs any better. The sensor is also very easy to check. I have ssen them clog up and also disengrate. Hope that helps
