02 with random misfire
Was backing out of the driveway and heard a pop and the engine light came on. car still ran and was giving a random misfire code p0300. Changed the plugs, wires and coils to no avail. Was going to take it to a shop but now it won't start at all. Someone said it may have jumped time I had timing chain changed less then a year ago.

Re: 02 with random misfire
the engine is 2.2 ohv. coil spark output is fine on all cylinders but compression when it ran was low on cylinders 1 & 4. but now that it won't start there is no compression on any cylinder. I can try the carb cleaner but I don't think it will help due to the lack of compression

Re: 02 with random misfire
I agree....with no compression, it's not going to start....
I think this is an interference engine, if it did jump time(tensioner went bad, chain broke), the valves are probably bent....sorry, but it looks like a major problem....

Re: 02 with random misfire
It is noninterference the chain broke on us before and I had a shop replace it. I was told that the aftermarket tensioners do not hold up. I am wondering it the new tensioner broke
