hi guys, the car developed a misfire a while back, so i had the coolant temps sensor - maf - plugs and coil packs changed, but still the same, then i decided to give it a clean and once over.

i gave the underside of the engine a jetwash off and checked the oil, i noticed that the oil was low and took a liter of oil, afetr doing this the misfire when and the car ran like a dream, now its started doing the same thing.

could this be because of a low oil level

Thanks David

 

Have you kept checking the oil to see if it has gone low again :S other than this take it to a specilist who be able to diagnose correctly the fault!.

 

i checked the oil and its fine, so it cant be that and i gave it an ecu reset but still the same.

i have been running the car on 97 unleaded for ages now with no problem at all and its very smooth, but this monday i put 30L of tesco 99 in and since then its been running like crap.

when i first start the car its fine but after about 20-30 seconds it starts misfiring badly and sometimes comes close to stalling, but once it gets warm it run fine.

Thanks david

 

have you checked for fault codes??

possibly coolant temp sensor?

 

yep check the fault coding and nothing came up, i changed the coolant temp sonsor 2 months ago, but it does feel the exact same thing as when the temp sonsor when pop.
