The engine misfires at 50 mph or more. Mechanic r/p air flow valve which did not solve problem. The engine warning light flashes but goes out at lower speeds. What do we dp next?
sounds like a electrical breakdown you could try checking the spark plugs,leads ,and coil packs,whens last time plugs were replaced? sounds like a electrical breakdown you could try checking the spark plugs,leads ,and coil packs,whens last time plugs were replaced?

code p 0301 is misfire detected cylinder 1====causes --negine mechanical fault---wiring---ignition/ fuel--injector--ECT/MAF sensor--ECM
as most misfires are fuel related rather than plug problems , check/replace the injector
sounds like engine misfire to me. but it takes a mech, driving to tell.
if engine misfires?
try getting a 60k mile full tune up.
open glove box, see opr guide? see service list, see 60k column (it repeats)
bingo.?
filters (air/fuel), fluids, spark parts. (generic list, RTM)
or login to alldata.com and click maintenance then full chart
then see all things in the 60k column, those.
Try cleaning the MAF sensor. It is delicate. It has a filament like a light bulb that detects the incoming air flow through the air intake. If the MAF gets a micro piece of dirt, pollen or any type of debris on the tiny filament, it can cause fault codes, skipping, engine shut down, poor gas mileage and etc. This can be removed and cleaned with a Mass Air Flow spray cleaner. Be sure to spray it about 10-15 times and let it dry before replacing the intake air pipe. On the other hand it could be a intermittent failure on a plug wire causing the skipping and misfire. Good Luck
Rather than take a stab in the dark replacing items - get the codes scanned and this should show what area the fault lies in. Normally if there is a fault with the MAF (mass air flow meter) it would normally show as a check engine light (MIL) - is this warning on?
So many things can affect these engines from O2 sensors, coil misfires, bad cable connections etc etc. - so best move get the car scanned.
Hope this helps (and saves money) good luck.
i have a 1995 jaguar xj6 3.2ltr.x300 model.the car has been running fine until yesterday morning when it wouldnt turn over at all.the battery is fully charged and now there is no dashboard lights.please help.cheers.
Hi,
I solved the problem by undoing all the HT leads and found water at the bottom, once I had blown the water out and dried up all around I reinserted the leads, tightened everything up, and prblem solved.
do a compression test ?? about 180lbs anything less and it could need a valve regrind ,if compression seems ok then plugs and leads and use the bosch plugs with the 3 electrodes (for voltswagon) champion are **** and missfire.if still persists change dist cap and leads
Plugs were replaced and all wiring was checked yesterday
Was wondering if the catalytic converters might be causing the problem.
Have not been able to receive solution
Still unable to receive info for solution
No help what so ever!
