Hello Everyone. I recently had diag done on an 06 eclipse gt mivec 3.8 V6 with a hard start, p0301 misfire when cold condition. Diag guy said to replace the maf sensor due to rich condition and there's a possibility of bent valves. I'm posting the results here to see what others think. Engine misfires on cylinder 1 when cold outside and trips cel p0301. It sounds like a sticky lifter on cylinder 1 when you first fire it up and then the lifter tapping noise stops after a few seconds. Runs great when warm with no cel. It had the parts cannon thrown at it, plugs, coils, injectors and fuel pump by the previous owner trying to fix the misfire. Previous owner stated that he did not start experiencing this problem until he changed the timing belt. Is it possible that the timing is off a tooth ? This is a sohc 24v 3.8 V6 with variable valve timing.
