Morning all.
After a bit of advice, I was out laning in the jeep yesterday and after going through a fairly deep ford (3.5-4Ft) she started to missfire quite badly. I tickled it back to a mates nearby and took the dizzy cap off and dryed it, sprayed the leads and checked the CPS, Camshaft sensor, and coil for wet plugs. Still missed, on both petrol and LPG. Checked the fault codes and it only reported o2 sensor (which I think is an old code). She does occasionally moan about water, usually the revs will drop off to ~500rpm and then rapidly pick up again, seems to sort its self after a few minutes. Not missfired this badly before.
Attemped a drive home with alot of popping and banging hoping (well youve got to give it a go, right?
) something may dry out/warm up and I did maybe 15 miles before it completely died on me. No spark at all.
I have had a CPS go on me whilst laning late last year, but that litterally just stopped. Does a failing CPS cause backfiring etc? I didnt think CPS because it was starting fine every time whilst I was trying to fix it.
Any ideas on where to look? I was going to test the CPS when I get home as its shown up fault code 11, but this can also be camshaft/dizzy sensor? not sure how to test that one.
Its a 1993 4L HO with 94K on the clock.
Thanks in advance
