HELP (misfire)
Can anyone suggest any reason why my 96 T5 2.3 (210,000 miles) manual keeps playing up the problem seems to only occur after the car has been driven for a while, it suddenly starts missing but when you put your foot down it runs OK (i.e just seems to be at fault on run on throttle). Also when the problem starts the engine idle is allover the place. Ive already replaced the MAF sensor once and seem to remember the car was stalling when that was broken, which its not doing now. Ive just bought another T5 so I can try a couple of sensors off that if need be. Any ideas would be much appreciated.

Check there is not an air leak from the manifold. I forgot to tighten a manifold nut on a mini once and the engine would tick over at 3-5000rpm and would missfire a lot.

1. Look for fault codes
It may be a problem with the throttle position sensor or wiring that only occurs when it's hot. Try cleaning the connector to the TPS, even better remove the throttle body and clean it and the idle air valve. |

RE: HELP (misfire)
Cheers for advise guys, will try both ideas although wouldn`t have thought it would be the manifold being loose as Ive had the car over two years now and havn`t touched the manifold, wiil check anyway on the of chance.
