My '91 Buick Skylark starts but when I give it a little gas it stalls. How do I diagnose it?

I recently had it at the shop -- they replaced the cam sensor, temp sensor and computer. We drove it home and it ran fine for an hour, then after it cooled off started this problem again. The shop is an hour away and I don't want to tow it back there. I love the v-6 power and mostly the car is in good condition, so I hate to junk it.

How do I diagnose it?Maybe you could call them and ask about the fuel pressure situation.It seems that it's running short of gas because of a poor fuel pump or filter.The shrader valve,that looks like a tire valve,is located in the fuel supply rail on top of the engine.Have someone turn the ignition on while you depress the valve with it wrapped up in a rag.Don't crank the engine.The pump will run for a couple seconds.Be careful,good pressure can shoot out a high pressure gas stream.My '91 Buick Skylark starts but when I give it a little gas it stalls.

it might be the fuel injegtionMy '91 Buick Skylark starts but when I give it a little gas it stalls. How do I diagnose it?go get about 20 feet of vacuum hose , like you see under your hood. Remove and replace each vacuum hose one at a time, so you won't get mixed up . Also watch for cracked vacuum connectors. This fixes more rough idle problems on older cars than you can imagine.My '91 Buick Skylark starts but when I give it a little gas it stalls. How do I diagnose it?
IT COULD BE ONE OF MANY THINGS BUT YOU HAVE A WARRANTY SO THE THE TOW WOULD NOT COST YOU.



THE ONLY OTHER THING THAT YOU CAN DO IS FIND SOMEONE WITH A SCANNER AND CHECK THE VEHICLES COMPUTER FOR CODES.



GOOD LUCKMy '91 Buick Skylark starts but when I give it a little gas it stalls. How do I diagnose it?have you tried putting a new fuel filter in. sounds like that might be the problem. they shouldn't be that expensiveMy '91 Buick Skylark starts but when I give it a little gas it stalls.

i assume...u have it tuned.....i find most bad running cars have bad plugs,wires,cap,rotor...ihate to say it but maybe u have bad fuel filter/pump....i seldom find a bad pump./filter but if you've tried all else its something to test. good luck....
