Hi there I was wondering if any of you could advise me, I have the above but ever since I bought the car the engine light stays on. I've had it cleared and remedied what I thought was wrong i.e breather pipe, CCV and front vacuum pipes, the light was cleared and stayed off for 100 miles then it came on. I've been to an indy who's cleared all the lights and given me a printout with an error of P170 fuel trim they say there were no vacuum issues, however they've pinpointed the cause as a MAF issue which will cost £338 inc. Seems a bit excessive when I asked whether this could be done as a DIY they told me the replacemnt MAF has to be reprogrammed to the ECU is this correct.
Would love to hear from you guys cheers Zak100
