Fiesta Misfire - coil, leads...or worse?!
Discussion
Sorry in advance for the essay guys!
My 53 plate 1.4l zetec fiesta began juddering a few weeks ago. I called the AA who checked and changed the spark plugs, sorted my leads, put a litre of oil in and did a quick check on the misfire (all seemed fine). They advised me to drive home, car still juddering but not as badly.
I took it out the day after and the juddering (especially in low gears) was much worse, plus the engine light was flashing. I carefully drove it home, did some Googling, ended up changing the coil pack and replacing the leads. Problem still remains.
I had a mobile mechanics visit yesterday who carried out a diagnostics test and found the 2nd cylinder was misfiring. This is a brand new coil pack so I'm assuming this shouldn't be happening. The coil pack was from Europarts and the numbers for the leads are the opposite from the original Motorcraft one (actually proving impossible as the leads aren't long enough, which the mechanics confirmed) which I thought might be causing issues...but there's no other way to connect, plus it doesn't explain the oil...
I checked the oil and there was hardly any in. I'd driven literally 8 miles since I'd put a litre in. Mechanic suggested it's more than likely a piston issue, given the rough idling, the smell of fuel when revving and the excessive use of oil.
61,000 miles on the clock and a knackered piston on a Zetec doesn't seem right, so thought I'd ask for a second opinion. I'm a day away from selling it as scrap, as the wheels need fixing and brake pads replacing, plus I'm coming up to a cambelt change.
Can't get it to a garage due to it holding no oil. Main symptoms are
Excessive oil use
Smell of fuel when engine running
Juddering in neutral
Over revving
Engine light flashing after driving more than 50m
Low rumbling from exhaust when revving (similar to blowing)
Any advice appreciated :-)
