Question about 1999 Pontiac Grand Am GT

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

I have a 2007 Suzuki xl7. When I first start down the road it seems to drive fine but within 1/2 to 1 mile it starts running very rough, leaping along. This goes for about another 1 to 3 miles. It runs...


ok and XL 7 but what engine options. gas, diesel, 2L , 2.5L?
what?
and most important , and never ever 1 time stated on this forum
what country.
leaping?

im not sure what you are saying.
it runs ok cold, and as it warms , the engine. it stalls.?
and what does same thing mean.?
my guess, it starts fine then stalls; hot.
but can you save the stall?

stalling is complex. can be many systems in the car.
but can be broken down to :
Ever did the 60k mile tune up,ever? if not why not.
never skip 60k\'s or the motor will run like garbage.


1: lost electrical power. to EFI .
2: bad engine, in that when it gets hot , it loses compression.
3: lost park. 1 or more cylinders, 4 or 6 you never said.
4: bad injection. 1 or 6 of them, flooding or starving.
5: bad fuel.
6:EGR sticking , usually this happens just before a stop sign.
7: if the stall was a bog and the fast right foot saved the stall, easy
the ISC is sticking closed.

Was traveling from out of state..stopped and refueled with diesel.. drove appprox.5 miles down the road doing 75mph and started losing power then shut off will not start again


your gelling up you need to change filter and get some diesel 911 and it will start going... if you try the 911 treatment first that might work.
