intermitant stalling at low revs

as above, when driving off boost, at around 2 - 3 k revs the engine goes to stall. Its not all the time, and does it more when the engines warmed up. If i put my foot down it will pick up, but sometimes if your comming to a stop it will stall. Have been told it could be the throttle poss. sensor? Does any1 else have any ideas? cheers.
they have nothing to do with this post, just not seen them b4 and quite like em!! (yes i am bored!!)

Re: intermitant stalling at low revs

sounds like it could be throttle position sensor or also on classic shape they had a lot of problems with air flow meters i had two on my96 and only thing i found that sorted it was going back to my original air box instead of cone filter

Re: intermitant stalling at low revs

Could also be your MAF. When mine went had identical symptoms. Do a diagnostic test and see what fault code it throws up. However, even if it throws up no code could still be the MAF. Another test you could is to start the car, let it warm up and then unplug the MAF with engine running. If engine keeps running it is your MAF, if it sops it may not be the MAF but no guarantees. When my MAF went no fault code, engine stopped when I did above test, the only reason i knew it was MAF was because of the symptoms and i eliminated all the other possibilities.

Probably doesn't help much hey.

Re: intermitant stalling at low revs

Should stop pretty much straight away. You may have a faulty MAF. Do you have a mate with a classic (same year)? If so, swap MAFS and see what happens.
