Car is surging badly when accelerator is pushed. it's bucking real bad and idling rough


Have you yet put Fuel injector cleaner in your gasoline tank because if your fuel injectors get clogged up by using the lower 87 octane gasoline that the impurities would slowly over time clog all your fuel injectors to the point that only small percentage amounts of gasoling would be injected by the clogging.

92 Buick regal 3.1 starts up idles up then shuts off


Observe the idle if it is rough, if it is it may be problem with the vacuum lines. They could be loose or there could be a leak somewhere. You may also need to have the IAC valve for the idle inspected. A good cleaning with a cleaning spray for carb would be good in the intake. See if you can rev the engine. If there is a loss of power or could not go to higher revs inspect the fuel filter. It may need replacing.

Runs rough at start up,then runs okay, Hesitiates momentarily when moving from a stopped position. Occasionally wont start and runs rough, then runs okay. This problem is intermittent


you have a bad injector, if you have A... as it states on the top of the motor 2.8, 3.1 L MULTI PORT and dies or idles really rough and the exhaust smells like strong gas. most likely you have an injector that has shorted or is shorting out and from my experiences usually after a road trip or using fuel injector cleaner or buying a used car. it will cause half the motor to not run or run poorly VERY POORLY or even burn out 1 injector fuse out of 2 under hard acceleration or idles but as soon as you touch the gas pedal dies. but only if it is a MULTI PORT fuel injected motor. ive heard you want to try and replace them with bosch injectors out of a 2.9l ford bronco/ranger. only attempt if you got the mechanical know how sometimes if not done right will leak gas because of the injectors being kinda different length. research before attempting.

ENGINE IDLES ROUGH, BUT RUNS FINE WHILE DRIVING. My car is a 1995 Buick Regal Gran Sport with the 3800 series motor with 212000 miles. The rough idle tarted after driving through some muddy and wet roads


go the cheapest route. replace fuel filter and add SEAFOAM to tank of premiun fuel. replace filter before 500 miles. then add SEAFOAM to gas every 3000 miles to keep lines.engine,fuel pump, and emissions systems clean, ETHANOL problem number 3000

3.8CI, V6 Engine will not start in cold weather.


I'm having a similar problem. The mechanic replaced the fuel pump relay and car ran fine for a while. The problem has since reoccurred. What I've read is that this could be caused by loose wiring connections or a bad ECM (computer) which is a notorious problem for this engine. I first thought it was a fuel delivery problem as well but I'm thinking it is more of a wiring issue.
