Fuel system problem. Clogged filter, kinked line, damaged pump.

Its probably the MAF or AFM or what ever the thing that measures air to the engine on a SR is called

When they break and through up errors the ECU puts the car into safety mode. Do you have the boost turned up on your car or is it cold out?

I second the faulty MAFS. Check your wiring. If all fails, check your ecu for codes.

He's right, it's your mafs.

I'd be willing to put 100 buckazoids down that it's your wiring. Somewhere along the line it's been severed from the ECU to the mafs itself.
