1998 cavalier overcooling and loss of power driving

ever change your fuel filter??? them cars are real bad for bleeding air from engine if you say changed the rad, had serious leak and topped it up again.. over cool sounds like you had a previous overheat and the thermostat is now stuck open....thet effects mpg because the long warm up time tricks the temp sensor into thinking its cold . temp sensor is todays choke on fuel injected cars. it tells computor to dump extra it can act like its "flooded" some temp guages work both the computor and the dash gage, some cars have two , one dash one computor, new costs around twenty bucks and filter should be around ten

Im looking at a 1994 f350 dually with the 460..its a five sppeed..i need it to pull my cow trailer..can i get 12 mpg pulling?? also, what do you think about this motor and set up in general...any help or...

Price is not bad, the motor set up is a great motor. I have never heard of any major problems with it. You will not get 12 mpg unless you are pulling empty on a level surface or a downgrade. A more realistic number will be 8-10 mpg with a loaded trailer at normal speeds. If you travel around 55 on highways you may be able to average 12 depending on conditions. You may also look to make sure it has a transmission cooler and weather or not it has turbo. All of these things will effect your mileage.

Car gets warm and starts hesitating on acceleration

this could be something in the fuel pump. As the cold motor draws more fuel, it may just be just ok for the engine, but after it is warm, it draws less and may "suffocate" it that way. Same goes for air filter, take a peek if it is not ready for replacement. Has this happened suddenly, or has it occurrend during a long perion of time?

89 k1500 Sluggish acceleration when warm

Sounds like fuel pressure. 44 is lean exhaust and 43 is knock sensor circuit. The engine can knock if it is lean. Try the filter first. Also check fuel pressure if you have a gauge.

Momentarily Sluggish Acceleration

Are you loosing power to the ecu when the car is shut down? most cars with an ECU that controls timing, fuel, or boost can be forced to relearn the car if the ECU looses power (called a "limp" mode). I'd look into this. Also are you getting any check engine lights? considering the description of the problem, this would help to diagnose. Try getting the car started and running normally, then turn the car off but do not kill the power to the car, just stop the motor from running...Fire the engine back up and try to give the car a good stomp on the gas and see if you get the same sluggish 2 cents... Good luck future auto DIY's

Poor Fuel Mileage 2006 Hyundai Sonata 2.4 motor

I don't know from where you bought the car but do you feel certain that typical causes such as fouled plugs or clogged air filters are not at fault?
Most dealers, even the shlocks don't normally skimp on the simple stuff but who knows about a private source?
That does seem low, especially the city numbers. I don't think Hyundai is any leader in gas mileage but they are better than what you are getting.
