Question about 1999 Pontiac Grand Am GT

1 Answer

Engine problem i think?

I start the car its fine about 5 miles down the road or so car will start losing power not shutting off but just wont accelerate. the only way to speed up is to put the pedale to the floor and it slowly picks up. the service engine soon light is on had it checked they said it was the oxygen sensor replaced that and still had the same problem. what can i do?

When a oxygen sensor is bad it shows and acts as if there is problem somewhere in the car. even though you had the O2 censor changed there is still a chance that when they ordered and installed it that it was defected. yeah its stupid but that was what i was told by a mechanic. but thats what that sounds like or maybe transmission.

2005 GMC Yukon Denali's computer shuts down after the truck warms up


sounds like a fuel problem, how many miles on vehicle? as a quick fix it would be worth using a fuel addative , you haven't said if petrol or diesel, if petrol get addative that covers the catalytic converter ,having a blocked exhaust system can cause engine to stall also get the OBD codes read as this will tell you what if any sensors/switch's are faulty

2000 GMC Sierra 3500 losing acceleration power


next time it happens try spraying water in mist form around the throttle body if it bogs, replace the throttle body gasket. if it doesn't bog you may have a bad wire wait until dark start the vehicle have someone feed the fuel very slowly and watch for arching from a wire it will be easy to see when it is dark, replace that wire.
