I have a 92 Laser that, for the most part, runs fine. However, every so often I encounter this problem where it will start lurching forward as I'm driving. It usually happens after I accelerate, and it doesn't stop until I turn off the car. Once it starts, the laser revs up to ~3k rpm, and then back down to ~2k rpm, over and over, and I can't accelerate past 40mph, and even getting up to that is difficult.
Iac tps or egr could be bad . find the specs and test them with a ohm meter.
SOURCE: Car stalls when accelerating
I would replace that tank (asap), so there can be a cap back on it.
With the cap off, the fuel system can't build up any pressure to hold the gas in the lines.
SOURCE: my car is jerking while accelerating and reaching certain RPM
I would look for a fault in the ignition system such as a cracked spark plug. Might need a scope check to put your finger on the problem

We are having the same problem. We are right now changing the crankshaft position sensor along with the intake and manifold gaskets.
SOURCE: 944 turbo throttle dropout problem
i gave my 944 turbo which had a idle problem. checked all the vacuum
attatchments, made sure all were connected. Checked coolant level.
Then cleaned the fuel pressure (part). ie the fuel rail attatchment, with carburettor cleaner then sprayed dry lube into it. Its running like a dream again. This part i am talking about has 3 inlets and is at the front of the fuel rail, when you take it out fuel runs out of it for a little while.
Hope this fixes the problem.
SOURCE: engine high rev at stop and slowly goes to idle speed.
I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck
