Hi all today I was driving snd all was good, but when I parked and csme back to the car and started to drive home all didnt feel right. When it got warm I went to put my foot down the spluttered and hessitated and then just went. I saw a puff of black smoke when this happened and it continued to do it when I put my footdown. And another thing at around 3k on boost I get a bad vibration and then it goes after a couple of seconds.


Any help would be great

 

Any one?

 

not easy to do a diagnostic ,,,it could be alot of different stuff...does it run on all 4 cylinders when at idle speed?is this a throttle related problem...if so...it could be the massairflow meter..it could be the coil...sparkplugs...plus plus plus

 

Black smoke is probably unburned fuel, sounds like an ignition problem. See if you have any DTC's stored but to be honest it could be a lot of things. Maybe try new plugs and leads first.

 

It had new plugs about a month ago, snd I do get the codes p0351 and p0352 which is coil a and b/secondary circuit malfunction

 

Make sure the leads are seated properly, the wiring plug to the coil pack is plugged in tight with no damage to the wiring. If all is ok I would be looking at a new coil pack.

What plugs did you fit? Are they gapped right?

 

I fitted ngk platinum plugs. They are gapped to 0.7
Ok cheers il go have a look at all the wiring and that

 

Rught fitted new leads and coil pack today snd still got the misfire there. Any other ideas what it could bead it starting to do my head in
