Hi all posted thread in wrong bit oops.
wondering if anyone can help me i own a 97 P38 4.6 HSE petrol and lpg and its drivig me mad. It has a rebuilt engine with top hats & kent cam I have replaced fuel pump, filters, coils, leads, plugs, all oils then sensers maf, lambas, cam, crank, tp, knock, coolant and finally the idle stepper motor.now this car is driving me mad as it has a bad misfire starting problems and sluggish. Had it plugged in 3 times 1st time no faults.2nd time no faults just a misfire but i noticed the 2 lambas 1 reads 2.5 & 2 reads 4.7.the landy man said check all plugs & leads as autologic cannot detect misfire but did a reset anyway then do a comp test so checked and changed plugs and leads ok still the same. 3rd plug in car ok no electrical faults at all he said its a mechanical fault not electric and running on LPG too much but car takes 5 or 10 min to heat up and change over to LPG. So previous to this i put a lucas cleaner in and he put a cleaner in too. My car wont start 1st time on the turn of the key or it will if you hold it on for about 20 seconds then the revs go to about 1000 then drop to 250rpm or it justs dies.2nd turn off the key starts then up to 2500 rpm.I have noticed the power and trying to chase the misfire. The car has only done 19000 since full rebuild then came power loss, misfire then poor starting/idling can anyone help
cheers mike
