On the previous engine I had two cylinders not working correctly for about 4 months then it spit out a third cylinder, engine has been replaced since.
Tank was dropped and pump filter replaced, no external fuel filter.
I am unable to double check all the work done. I'm not exactly the car literate, working on it but not there yet.
Will definitely double check the o2s across he manifold! It was just replaced (against my direction to the mechanic) and the problem did start after that.
Check engine light bulb is working.
Horn relay did not work.
Will try these out, I will see if I can find diagrams to figure out the ground points.
If a Bosch 'Universal' O2S was installed by splicing wires that could be a problem. A direct fit Bosch O2S by itself could be a problem.
