Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / July 2006MERCURY SABLE 1996 SERVICE ENGINE SOON
The "Service Engine Soon Light" keeps coming on. My mechanic's code reader shows P0303, something to do with one of the cylinder? After lot of work and hours on the car, my mechanic is thinking of changing the computer of the car because this may be caused by a problem in the computer itself, giving false message. When the code is erased, the car works perfectly for few minutes or hours and the signal comes on again. At 100-110 km/hour or more the car shakes and slowdown before getting strong power again and go. Sometimes, the Service engine soon lights at the same time as overdrive green light. It appears that a computer for my car is hard to find. Anyone with an idea to solve this problem? GOITA thats a cylinder #3 misfire. > The "Service Engine Soon Light" keeps coming on.

Bad in jector, plug wire, coil, weak cylinder compression, this assumes you actually have a driveability issue, which by your desciption you do. There is no magic bullet here. > Any suggestion for solution to the cylinder number 3 misfire? > [quoted text clipped - 13 lines] >> >> GOITA >The "Service Engine Soon Light" keeps coming on.

It appears the "mechanic" cannot find the intermittent #3 misfire. Should be easy to find a computer at a salvage yard but that probably will not fix the problem. > Anyone with an >idea to solve this problem? Change shops. Don www.donsautomotive.com >GOITA |
