Title: 8v misfiring
Post by: cw3514 on 10 October 2008, 13:52

Hello

I've got an R plate 8v with AGG engine that has today decided to start misfiring around 2000 revs in 3rd and 4th.
Did a service on it on Monday, changed oil, plugs and air filter and all was fine, now it misfires grrr.

Anybody got any suggestions before i take it to the garage? I've, probably about 18mths ago, changed the crank sensor, the MAF, cleaned the throttle body and replaced both of those dodgy relays i think so i'm a bit lost as to what it could be. car has 90k on the clock. did cambelt at 60k.

Thanks in advance

check your air filters pipe is properly connected to the throttle body as it can slip off a tad and suck too much air in. (may have dislodged when u changed the element)

Check the clearance on all your plugs are the same, if one of the plug boxes had been dropped it could close the gap causing the mis. Had me bamboozled when i serviced my focus a couple of years ago!!!!
