Very odd problem

[Sunburn]

Hey guys, hoping some one can help,

1995 GPX

Ok, I have been having problems with my car stalling at the lights and stalling whilst changing gears.
This has nearly killed me a while back, I was going around a tight corner, and dropped a gear but missed the gear change, at which point engine stalled with no power steering I nearly went off the road.
I dont understand whats happening, can anyone advise...?

In addition to the above....
Im also getting some REV hunting whilst on stand-still, although this problem is intermittent and finally... this is very odd.
If I pump the brake pedal, my revs rise to about 1200, if i stop, the revs drop and the car stalls

Does anyone have any ideas what the hells going on?

Thanks guys.

Geoff

stepper motor ... common problem, with the fto. take it off and give it a good clean

[crayzidane]

...and full service including spark plugs front and rear if not already done

Cheers for your fast replies, I know next to nothing when it comes to cars, but ill give the stepper motor cleaning guide a go, and see how I get on with that.
on a separate note, is the fuel filter easy to replace? if so is there a guide on this forum?

I think the car could do with a major service, ill start pricing up the parts.

Cheers all.

Stepper is easy - 10 minute job DIY

Fuel filter isn't quite so straightforward AFAIK. One for the mechanic unless you're handy and not afraid of engine work yourself.

Sounds exactly like the stepper motor. I had the exact same issue earlier this year. Cleaning it might work but if not you can pick up another one and it's a five minute job to swap it. Borrow one from another FTO owner if you need to test it but I'd bet the farm on the stepper here.

I concur. If you're gonna be playing around with the stepper it might be worth your while to take off the throttle body and give it a clean too. It's the thing directly above the stepper motor. Take off the intake and open the buttlerfly valve with your finger of the throttle cable and give it a good clean.
