slam acceleration... nothing happens!!!
« on: 13 April 2005, 20:54 »
Oh no.  Took the car out again to listen for the knocking noise from the front.  Went to accelerate and the thing did nothing.  She just sat there not increasing speed.  This happens at any speed and any rpm.  If i back off, then very slowly depress the accelerator she will slowly increase in speed.  Stationary, if i blip the throttle she will pop the exhaust, sometimes she won't rev at all.  It even sat at 2500rpm for a few seconds until i blip the throttle a few times.  What on earth is happening???  I feel i have been sold a dud motor.

Could be a MAF sensor fault, try swapping it.

that would be the large grey thing usually sat ontop of the air filter which is currently sat ontop of my table work top.  would a garage be able to tell if this is knackered or am i on a trial and error trail.

It's fixed.  I just took the MAF off, got the old WD out, had a look inside.  Couldn't get into the electronics bit so just squirted everywhere.  Stuck it back in place.  Hey presto, 6000rpm again.  shamown.  now just to get rid of that knocking noise.

Out of interest what kind of injection system is it?

I've come across this a few times on the digifant injection system where the airflow meter flap gets clogged up with crap
