I would have the catilitic converter checked. when they clog up you loose power and burn more fuel it could also explain the hot engine as the exaust can not escape. hope this helps!

My 89 Grand Prix with a 2.8 just dies going down


Sounds like a bad fuel injector. Back in the day we would let them runout in the parking lot and when they stalled we would rip off the intake plenum as fast as possible and ohm check the injectors. They should be around 13 ohms. If they are significantly less, say 3 ohms, than those injectors are bad. This system bank fires the injectors. Meaning that all three injectors on the front back fire at the same time and all three of the injectors on the back bank fire at the same time. If one injector hoes bad it will shut down the whole bank which will stall the engine.

check the pcv valve, it will **** up oil and burn it if bad, and also check the hose to pcv valve. depending on vehicle the price for a pcv valve is very reasonable. pull out pcv valve and shake it ! if it rattles its ok. but if not replace it. have a good day !! ( positive crankcase ventilation ).

2000 grand prix, 3800 when it warms up losses power


I would have to say the fuel/water separator filter is clogged up. The filter will remove water and crud from the gas. It looks more like a small can under the car. If the car set up with a low tank of gas, water will condensate inside and once the new fuel sloshes around it gets all this junk off the walls of the tank and that gets sucked in the filter. Try and replace that first..

Hi i have nissan 2001, consuming lot of fuel,


Take your foot of the gas. Fast starts ie speeding away from stops and starts burns more fuel.
Make sure your air filter is clean to allow proper fuel air mix ratio. If dirty replace it.
Lighten your load.Don't carry around a lot of dead weight in your truck. The heavier the load the more gas used.
Use a 91 or higher octane gas, this gas will burn hotter and give you more power thus again needing to step on the throttle less to create momentum
Try to maintain speed limit. speeding cost more.
