I have a 1991 laser turbo that is all stock, it revs up and down when you start it and then after a while just dies. When you put it in gear the cars moves slow and wont rev up at all. It throws up codes for the intake air temp sensor, TPS sensor, and other sensors. I checked the TPS sensor and it was fine. I thought the problem might be fuel related but I can't find anything wrong. Hopefully someone might know a common problem these have.

Ha! I know of about 73 common problems these things have!

I had a similar problem recently. The VFAQ listed above should be very helpful. My problem ended up being the EGR valve leaking. There is also the possiblilty of an air leak at the throttle body gasket, although that wouldn't seem to explain the car dieing or having no power.

have u checked ur fuel pressure? It could be the fuel pump is weak. Try cycling ur ignition key on and off a few times to build up pressure and see if it will idle correctly. good luck

I have tried about everything. I took off the throttlebody, cleaned it all out, put a new o-ring on the biss screw, blocked off the Egr valve, and beat out the catylitic converter. All this did was steady the idle and make it run a little better, but the car still has no power in drive. I unhooked the fuel rail and checked the fuel pressure right out of the fuel filter, it was 60psi to begin with then built up to 70psi. I think problem is the fuel pressure regulator, but not sure if that would make my car do this.

You should check your fuel pressure with the rail still hooked up because the fpr is located at the end of the rail. 'T' in a fuel pressure guage somewhere between the filter and the rail. B&M sells a fuel pressure guage that goes right on top of a stock DSM fuel filter.

Yeah, your deadheading the pump. The pressure will then read the max the pump will put out.

Get the B&M gauge that Natedogg suggests, I got one works fine and it's pretty cheap.
