hi peter
ive had the car over a year and it already had hks exhaust and air filters.took it to hiteq and had a phase 1 comprising a chip for the ecu,hks downpipe and decat pipe.
started the car this morning and the engine kept dropping the revs itself(as if it was cutting itself out).as it warmed up it was ok and i could rev engine ok.but on the move at 2500rpm it cuts the revs and backfires.what do you think?air flow sensor or meter?ive checked intercooler pipes but there ok.
any ideas appreciated as i dont really want to drive it 170 miles back to hiteq if i can help it!

Hi Chris,

Sounds like you a fuelling/ignition problem to me but I guess you need to get it back to Ian for him to have a look. Sorry I can't be of any further help...

mass air sensor = air flow meter. There are two of them. Probably need cleaning (there is a thread by John Lowe on this).
