That MAF is going to need a decent code reader on it to be sure.  However, my initial feeling, given that its reading high and low, is connector.


As JB says, run it about for a few days, see what comes back

I,ve got rid of the codes for the Air Intake Temp and the MAF sensor but 21 has popped up now

21   Throttle Position Sensor (TPS) Voltage High

so i've just cleaned the connector on the TPS and will report back later   

[mrjimbo]

All codes now gone   

I'll check again in a couple of days, just to be sure but all seems OK now.
Just hope the mpg improves

Could be worse - my MPG dropped to 17mpg

I don't normally take much notice of the mpg as i do more short journeys than longer ones at the moment but i know that when i checked in the summer it went down to 28mpg and i couldn't really find a reason for it, but i recently changed the cambelt and the mpg did improve but never managed to get a chance to find out how much it had improved and there were no codes present after doing the cambelt and i checked the codes again last weekend and they were all clear then aswell but when i only got 24mpg on a 280 mile journey i wasn't impressed.

All clear now though. Got a longish journey tomorrow so i'll check mpg then and see if it's improved

Right, just back from Brum which was a round trip of 164miles and used 28.25lt of fuel which works out at 26.4mpg so the fuel consumption has improved slightly which is good but not brilliant seeing as it was all motorway and dual carriageway.

When i came off the dual carriageway close to home the engine symbol came on as i came down the slip road. It went out after about 1/4mile and hasn't come on again since. It starts and runs OK and idles OK. I've just been out and paperclipped it and it's showing code 16

16   Knock Signal Circuit 1

any ideas what thats all about ?
