i posted this thread yesterday why did it dissapear?

mad: hi everyone ,i got a weird problem ,my car starts to stutter and hesitate after about 20-30 minutes of driving.

Before that,it runs fine.

no codes pop out on the scanner,no check engine light,no hose disconnected.it does that on all gears also between 3000 and 4000 approx.

2 mechanics said its misfireing.The fire cuts somewhere.we changed the spark plugs,wires ( wich i was sure wasnt gonna do anything ) then the crank sensor,coil pack,module and no change. the car misses between 3000 and 4000 rpm ,if you rev it more then 4000 it seems fine.

what else is there to check? the car starts good,no fuel pressure drop either.

ps ; whoever built this car,can you please open up a garage so we will at leats know 1 mechanic that knows how to fix it,cause everywhere i go and try to fix this car, no one knows what their really doing,just changing pieces left and right.

you could email me directly at lachachmtl@hotmail.com

passsed 3 long days at the garage so far, no problem solved yet :frown: :frown:
 
what kinda plugs did ya put in it? get some fresh autolite #23's and set the gap at a tight 30
