Question about 1996 Buick Regal Olympic Gold

1 Answer

Random misfire on first start gets worse w/ low gas

Car doesnt wanna start after sitting several hours w/o a touch of starting fluid. Then it purrs. After i drive it for a while and try to restart it starts right up but misfires and ses light comes on. i hold gas halfway to floor and after 20-30 secs car finally hits 2500 rpms and stays there on its own for bout 5 secs and then idles fine. It does this consistently but once it idles smooth doesn't miss again till next start. i believe it is fuel related. Thought maybe i had water in the gas and it was getting mixed w/ fuel while driving but i need help. Dont wanna replace fuel pump unnecessarily. Is there a way to test the fuel pump? How?

Random misfires could be gas related- low fuel pressure, vacuum leaks or air leaks upsetting the air/fuel mixture ratio, clogged air filter or fuel filter. Could be ignition related- worn spark plugs, possibly. Or could be an internal mechanical problem-possible valve train malfunction.
Start with a fuel pressure test. check vacuum hoses for leaks, check intake manifold and throttle body assembly for leaks. If you have an exhaust leak at or near the engine, can cause misfires. Air going into the engine is metered by the mass air flow sensor in the big air boot on the throttle body. If extra air gets into the engine through a vacuum leak or a loose hose, the engine computer won't know it, so the air/fuel mixture will be too lean, resulting in misfiring. Several things to check-good luck.

what type/size of engine? what year model truck? several things to check for a random misfire. also , how many miles on the truck? coils are a possibility but they usually set specific cylinder misfires if it is equipped with coil on plug ignition system. a vacuum leak or low fuel pressure can cause a random misfire. also broken valve spring can cause the misfire because it effects the engine vacuum.

Transmission issues revving up and not going in gear smoothly


I sounds like you may be low on transmission fluid. Its hard to say with the limited information yuo have given. If you put it into drive and the vehicle sits there and you give it gas and the engine revs up and then slowly starts moving, it is a transmission problem. If it is low you may have already done irreversible damage. The problem will get worse very quickly. Check your trans fluid immediately.

2000 Astro Random Misfire


This sounds like a classic GM plugged catalytic converter symptom. If you like you could remove the oxygen sensor in front of the cat and try driving it. With the sensor removed, the exhaust can escape a little more easily and will drive better if the cat is the problem. If you have the right fitting and a gauge, you could actually measure the back pressure at the oxygen sensor hole. It should not be any higher than about 2 psi at 3000 rpm. I have seen this problem several times now on these vans and I'm almost certain this is your problem.
Hope this helps,
Dave

Car won't start!!


AmyLynn001, 1st thing, let the car sit for a couple hours (because u smell gas, it's definitely flooded). Turn the key to start (do NOT touch the gas pedal!! Cars are designed now to start w/out touching the gas pedal. If u do, u will flood it, and make it even more difficult to start) When u turn the key, only hold it to turn the engine over for no more than 10 seconds. If after the 10 seconds it doesn't start, turn key off, wait about 10 seconds, repeat. (this is to reduce wear and tear on the starter, and to not run the battery down real quick). It sounds like several problems coming together caused this. U state that the car needs a tune up, it's likely the overheating, need of a tune up (car not performing to optimum efficiency) and pushing on the gas pedal, resulting in flooding, all came together to create this no start condition. Eliminate any one (preferably all!) and u should be able to start the car. So, hopefully just letting it sit and not touching the gas pedal while attempting to start will be enough to get u back on the road, then get that tune up soon. Let me know how u make out.
