hi their
this is the first time that i have posted on here but i have been an active reader on here for the last couple of months.
firstly ill give you a bit of background to the problem.
car initally had a head gasket problem caused by leak on the water reservoir, the car developed this leak on a long drive back from germany so the water was chucked all over the engine in an attempt to get it home.
so set out to repair this, car had the head gasket done, new radiator, fan shroud, water pump, spark plugs, head bolts, cam belt all fitted.
car was struck up and had a misfire on three cylinders, diagnostic said mis fire on 1,2 and 3.
so purchased three new coil packs for the car and had them fitted, cleared code.
car ran fine for approx 40 miles and again had engine management light and mis fire and loss of power.
diagnostic read mis fire on 1,2 and three again, so to be on the safe side bout another three coil pack and replaced the other old three (so car now has 6 brand new coils).
car still had engine management and misfire.
so went back to the beginning and re stripped the head, head was sent off to be tested checked skimmed and repaired where necessary (it required two valves), re did all the gaskets again, re checked spark plugs before putting it all back together again.
timing through out this has been checked at least a dozen times and its right.
but car still has the same problems.
it will start but misfires, engine management light still on, and im now lost with what to check next.
throughout all of the above we have checked wires, sensors, leads etc etc and everything seems to be correct.
can anyone shed any light on this please as i have no idea what to check next and really dont want to have to take the engine back apart again, i have looked through pages and pages of forum topics but havent found anything like this!!!
please help!!!!!!
thank you in advance
