Question about 1994 Chevrolet Caprice Classic

1 Answer

I have a 94 chevy caprice 5.7 I recently put in new radiator fluid, changed gas filter, changed the oil, and I went to an autozone and bought a fuel injection cleaner, put it in my tank i had a quarter tank of gas, i drove it like that for a while until i filled it up, and ever since then my car has been acting so slow and also burns too much gas. I was told by a mechanic that the fuel injectors might have gotten clogged up, and we removed the fuel injectors and took them to be cleaned, and we put the car back together and tried it but it still had the same problem. And now im told by a friend that it might be a sensor but i dont know what sensor it could be. If you could please get back to me with any helpful information i would appreciate it.

Hi,
Myself and other experts will try to solve your drivability problem, but I do have a few questions; How many miles are on the vehicle? Are there any check engine lights that come on?? Before all the fluid changes, how was the engine performing? Was the fuel tank filled up since the quarter tank and cleaner was added? When you say "acting slow", when do you fell this occurs? No need to rate the solution just yet, this is a clarification. Thanks.

Car has been sitting in garage for past 10 years, on blocks. what do you recommend before trying to start? it needs new battery.


you need drain fuel tank.fuel tank probably need to be removed and cleaned out to remove all sediment in bottom of fuel tank.remove each sparks and label them.squirt some clean engine oil down the spark holes into cylinder bores to help lubricate cylinder walls and help seal the piston rings to build up compression.replace fuel filter.best to change spark plugs and wires.check all brake hoses they more likely old cracked. i would change brake fluid bleed out all the old brake fluid out of the brake system.also change power steering fluid and change transmission fluid and filter also change engine oil and oil filter.replace the antifreeze and all the coolant hoses and radiator hose.replace thermostat and radiator pressure cap.replace battery and add new full tank of gas.you should be ready go. check ignition timing also.

I have a 1994 chevy caprice classic. i know gas has went up, but my car is sucking up gas extremly bad. i already changed the fuel filter and fuel pump and the distubtor and cap, still same problem. what...


You did not say which engine you have. If it is the 5.7L V8, your only going to get12 or 13 mpg. You might try a new set of spark plugs and a new air filter. I put the E3 plugs in my 4.3 GMC and the mileage jumped dramatically. They are a little pricey, but what isn't these days?

Automatic Transmission shifts late and rough after warm


Try servicing the tranny fluid if not changing the fluid, if the problem has existed too long it may be time for a new tranny.
