i have a problem with my 1988 toyota pick up.It starts good but when i go to give it gas it chokes itself out. They oxygen censor might be bad. Could this be causing the problem. The truck has a slight fluder when it is running. I can drive it but i have too ease on the gas when i first start off. the lines are good and the fuel pressure is good. Please help this is driving me crazy.


>>>*The first instinct when dealing with a computerized system is to suspect a sensor having failed.

But severe hesitation or stumbling associated with increased throttle load is nearly always fuel related.

The action of opening the throttle simply adds air, on a carbed vehicle a pump is used to increase the volume of fuel available or the engine will do exactly as you describe.

A computerized system will demonstrate exactly the same way if it cannot enrich as the throttle is opened quickly.

First is to check the ignition timing, then reset the TPS. Next is a serious vaccum leak, injectors. The description suggests lack of adequate fuel under load.....*EB
