Bad misfiring on 3 cylinders... Stranded need help Hey everyone, So I need some direction and can't figure this one out. So about 6 months ago my car started misfiring while I was on a trip to California from chicago. I fixed the problem by changing the plug wires. I still occasionally got a bit of an engine stutter when putting the throttle to the floor, but didn't seem to much of an issue. Now here's my problem im currently on the road in Nashville. And after 5 hrs of driving same exact problem started again. Out of nowhere my car started misfiring wasn't a gradual loss of power but instant while cruising on the highway. I pulled over tried changing spark plugs didn't fix it. I only had an he to Nashville so I drove on 2-3 cylinders the rest of the way. At one point I pushed the clutch in going 60mph and the engine died. I popped the clutch and got it running again and it fixed the problem instantly for another 30 min before it went back to misfiring. I just changed all the plugs again, tried a new coilpack. But nothing, I can't imagine the plug wires are bad again, but it's the same issue as before. I do have one cylinder that has a helicoil in it, and at idle that seems to be the only cylinder misfiring, as I pulled each plug while running at idle. But when driving an especially under load the car is terrible running on max 3 cylinders sometimes 2 I've brought the car to a shop and they don't know what the problem is. One thinks it's a clogged cat. I really need to get back on the road, does anyone have some direction? |
