    P38 Missfires on Petrol but runs perfectly on LPG

    Hi Lotofnames, Just picked mine up and it is running sweet as a nut. I changed the inlet manifold upper and lower Gasket and swapped one injector for another on the advice of the Guru. He said there was nothing electronically wrong therefore No 4 cylinder must have a mechanical problem. With...

    P38 Missfires on Petrol but runs perfectly on LPG

    Hi all, The Guru has an educated guess and recons it is sucking in air from the manifold gasget. Or the injector isnt working properly. So my next job is to change the injector and replace the manifold gasget. Stay tuned and I will report back when I have done the job and got it all...

    About to take the plunge!

    Hi AngryBritain If you want it, buy it! Mine is year 2000, it had 48.000 on the clock when I bought it 4 years ago. Its now got 81.000 on it and it ran sweat as a nut. I paid £11500 for it then. It had a FSH which I think is very important. I do have a misfire problem now but after 4...

    P38 Missfires on Petrol but runs perfectly on LPG

    Hi all Sorry for the rant in my last post! It was late and the problem got to me. Removed the MAF sensor to give it a clean and it was in pristine condition, no soot at all. The car has a full service history so I guess a succession of new air filters is responsible for that. I also...

    P38 Missfires on Petrol but runs perfectly on LPG

    Hi all, lotofnames Its been a couple of weeks now since last post. Waiting to get car in to Guru's timetable. Very frustrating! I must say there was an air of confidence when I saw him! Well, he had the car for a couple of hours and said my right hand LAMBDA sensor was reading low which...

    P38 Missfires on Petrol but runs perfectly on LPG

    Hi lotofnames Is the engine new, second hand/or reconditioned? Earlier in the thread people have mentioned that when you have your fuel adaptations reset the car will need about 100miles to get reacquainted with itself again. The reset sets the car back to its defaults like when the car...

    P38 Missfires on Petrol but runs perfectly on LPG

    Hi All A couple of questions bearing in mind that the engine only misfires on pot no 4 and intermittently on No 8. 1. If a LAMBDA sensor had gone the misfires would occur on the bank of pots it relates to? 2. If the MAF sensor was duff then misfires would occur randomly at any pot? 3...

    P38 Missfires on Petrol but runs perfectly on LPG

    Hi all rewmer - I did note the MAF reading and recalled what you had said earlier in the thread. I actually took the MAF readings with me. I explained that they were high they said it was due to the misfire. They also said that they wouldnt do the adaptations until the misfire was fixed...
