The motor is only 397km old, 3 weeks old.

She started yesterday and ran for 3minutes then the motor started to shake and the idle droped to 500rpm then stalled. BITCH. Everytime I start her she runs fine then about 2-3 minutes later the bitch won't idle and starts to shake. I tryed to hold the pedal down but it only makes things worse and I try to hold the revs at 2000 but she still stalls. when the motor got built (pro built by mechanic) everything on the motor is new. Checked everything but can not find problem.

Can some one help me on what they think it could be, just incase I missed something.

I need to do some of this soon

 

did you try the MAP sensor?

 

Yes and checked all the pins in the computer and all the sensor units just incase

 

397km's? Damn, I wish I knew how to convert km's into miles..

 

It's 248.2 miles old. power suply is 12.8vdc. checked the Bosch system all fine leads and plugs are new, timings correct, dam the motor is new, injectors are fine

 

She runs fine for 2-3 mins then craps out? Hmm That is strange. The shaking and not idling sounds like an apex seal, but it's not if it runs fine for a couple mins and then starts shaking, then thats not it.

 

She idle's fine for 2-3 minutes during warmup then sudenly starts to shake and then she stall's. The thing I don't understand is that she runs fine when she first starts up then for the rest of the time that she warm it does it (if I start it then turn it off). If I leave it till the morning shes fine for 2-3 minutes then does it again.

 

what kind of engine management are you running?

 

could it be the map works when the cars cold and when it warms up it leans out too much?

yeah thats what i was thinking, it brought me back to when my car wouldnt start with dacs maps and the temp outside was right at the post start threshold... it has the timeout, sounds plausible.
