Hello Chaps
Sadly I have lived with MAF failure for few months now and finally got around to repairing the culprit...........MAF so innocent and clean but totally kaput!!
SYMPTOMS OF MAF FAILURE
1. Morning start up lots of backfire (popping noise under bonnet) and a total embarassment when you drive a Mercedes specially!! Car moves very slowly and hesistantly as a result for a while and pedestrians think you are curb crawling!! Pressing the accelerator makes movement even slower until car warms up.
2. Car would move very slowly forwards and lacked power and symptoms got steadily worse.
3. Car felt very underpowered and heavy - like it was carrying a lot of weight.
4. Some gear changes were not firm and clutch slippage would occur not all the time but happened.
5. The whole MAF failure is slow and symptoms got steadily worse and profound with time.
6. Going up hills got slower and slower (this triggered my thoughts something not right). Eventually a 10% incline hill climbed at 15MPH!!
7. Gearbox showing signs of slippage during change oddly on the same spots on the road journey!!!
8. Engine rev counter did not go beyound 2K revs per minute when driving but would go through whole range when stationary.
9. Car slowed down and hesistated as soon as a incline was met on the road.
10. Pressing accelerator mad no differnce pressing it would infact make car hold back on power and hesitate more!
11. Manual selection of gears made no difference - car slowed down further to clawing pace car just confused.
12. Petrol consumption higher.
13. Cleaning a clean MAF made no difference.
14. Start up engine worse point with backfiring and slow movement of car until warm.
15. Car just generally drove like a slug.
16. Engine would die or loss revs at traffic lights when coming to standstill - rev counter would flicker and level off.
I replaced MAF today bought from German and Swedish Heathrow for £45+VAT took 5 minutes to do - dead simple. Car revs freely through complete range when driving and gear changes are firm and confident. Also kickdown is back - sadly missed until today.
I hope this helps.
