Your problem could be caused by numerous things, how well was this car maintained? A good tune-up should rectify your problems, oil change, air filter change, tranny fluid and filter change, plugs and wire's, coolant flush, timing belt, thermostat, fuel filter are all things that you should have done if they haven't been done recently. Let me know what you have or haven't done on the car and I can try to diagnose further.

Hope this helps

I have a 2006 chrysler pacifica. The engine light is on. It has gone off after i have put in super high test gas. Gas mileage is poor. When I try to rev it up in park it won't go over about 3000rpm. ...


My thoughts on your problem. First when you rev it up in park it shouldn't go over 3000 rpm the computer wont let it. Did you have the check engine light read to see what the code is? when you say the gas mileage is poor are you comparing it to what it once was? As far as the miss goes is it a constant miss or a random miss? if you could answer these questions I should be able to help you further

1987 Dodge Caravan getting poor gas milage


If you suddenly are getting poor gas mileage your O2 (oxygen) sensor may have failed. The O2 sensor helps dictate how rich or lean the fuel mixture is. If it fails the engine's computer defaults to a rich mixture so not to burn a valve or run too hit. This can be checked and if need be easily replaced. And yes if the van is over-do for a routine tune-up this is always a good investment. Make sure to check the air filter too, if she's dirty the engine will starve for air and get poor mileage.

I hope this may have assited you,
Tom

I have a 2000 hyundai elantra and the po734 cade is on and i do not know what i should do do you have any answers and also i am getting horible gas mileage


P0734 means that your transmission is slipping. This being the case, it is not surprising that the gas mileage is poor. You will need to have your transmission checked out professionally. Take it to a trustworthy transmission mechanic or to a dealer. Get a second opinion before you have any work done.

Need info on timing belt 1998 hyundai elantra


The timing belt is normally replaced at 100,000 km (approx. 60,000 mi), but must be checked for wear and tear starting 75,000 km(approx. 45,000 mi) along with a major tune-up.

The switch near the shifter is the ECT (transmission control) which selects NORMal driving mode, and PoWeR mode. It is the battle between economy (NORM) and driving performance (PWR). As tested, the PWR mode delays your A/T upshift to a higher RPM. This utilizes your engine's higher revs, but really cuts into fuel economy.

Hope this helps.

2008 Toyota Highlander Sport AWD when starting off the engine seems to rev fairly high for very small vehicle movement. At idle engine revs around 1000RPM. Gas mileage is poor,17MPG for about 80% city, 20%...


yes it is normal many customers complain about how the newer cars are not as responsive from a stop basically you have to hit the gas then the car goes seems to rev high to people with not a lot of movement becausse of this its because the newer cars are throttle by wire when you hit the gas it sends a electrical signal to the throttle to go instead of a few yyears back they were you hit the gas and the cable attached to gas pedal pulls back throtttle much more responsive hope this helps

Poor acceleration, poor gas mileage


I have the same problem as talked about above. 2002 Hyundai accent gsi. HORRIBLE gas mileage. I only get about 320 km per full tank. My driving habits are good. i took it to the garage and they put it on the computer and no error codes showed up. Question: Can a MAP sensor be faulty but NOT show up on the computer diagnostic? I had my O2 sensor checked out and my exhaust, and changed the flex pipe. Car runs pretty good just horrible gas mileage and kinda crappy power. Changed fuel and air filter. Cleaned the fuel system entirely ($80 at garage not $4 bottle).

Anyone ever use a resistor in the MAP sensor?
