i dont know whats wrong!!!

i have an 87 camaro, 2.8L. today when i started driving my car started acting funny. when i accelerate from a stop, coast, or a low rpm it hesitates and jerks, or chugs for 10 to 15 sec into the acceleration. it doesnt gain speed during this. it also just died idling in a parking lot. whats wrong ??? im really worried

What does the tachometer do when this is happening?

Re: i dont know whats wrong!!!

Loss of power points to a fuel or compression problem. Check fuel pressure and do a compression test. This should begin to point you in the right direction.

I would lean more towards a fuel or ignition problem.

Re: i dont know whats wrong!!!

Check fuel pressure make sure it's correct.
Could check spark plugs and make sure they are not damaged in any way.
How much mileage is on the car?
When is the last time you had engine work and what was it?
Are your fuel injectors stock?

Re: i dont know whats wrong!!!

Also run the car in the dark with the hood up, check for spark leak around the coil or wires.

Also mist engine with water, spray bottle. If ya see any fireworks from either, bad wires.

Re: i dont know whats wrong!!!

so i changed the spark plugs and it got 80% better im changing the wires today so well see but im confused about the obd stuff i did the paper clip thing and got the code and its saying misfire but i have a kill switch on my car that cuts power to the fuel pump when the switch is on no fuel can't start car you know and the service light comes on when i put the keys in but if i turn the kill switch on the light goes off and turn the switch off the light comes back on so im wondering if its actually a fuel problem!!! idk!!!
