    thanks but i put a new battery in and it solved the problem the computer must have been losing the memory for the throttle position sensor and when I started and ran a while it learned some new settings and now runs fine.
    thanks for the input
    have a great day

Idles rough and rmps jump while driving.


You may want to have the throttle position sensor tested. You should be able to buy a Haynes or Chilton manual for directions. A new one TPS is only $60.00. Test before you replace.

Car starts when it's jump but won't start again could it be the starter


the battery in your in car is maybe drained or damaged or the alternator which suppose to charge your battery is not working so the battery remains uncharged. One way to know if battery is not being charged, jump your car and disconnect from jump leads and take out any one of battery terminals. If engine stops, then your alternator is not working and if it remains idling, then your battery is faulty. Replace battery and see if it works.

I just buought a 98 Volvo S70 T5, the car sat for abit, to the point were It had to jump it. to start. ran great for the next 2 hours off and on mybe 7 diffrent starts but it never running for more then...


It could be a number of things:
  • Bad connection or corrosion on battery cables
  • Dead cell in the battery would prevent it from charging fully
  • Bad or worn drive belt would slip, preventing the alternator from fully charging the battery
  • Bad alternator
If the car will run at idle with all accessories turned on, the alternator is good and you should concentrate on the battery and battery cables. If the car won't idle, then the drive belt and/or alternator could be the issue. If the car starts everytime when it's cold and only gives you a problem starting when the engine is hot, the starter could be the issue. A bad starter will often work when it's cold (after sitting a few hours or overnight). When a bad starter gets hot, it takes more and more power to get it to turn over.
Overall, I'd have the electrical system checked out. Most chain auto parts stores (Autozone, Advance Auto) will do a complimentary electrical test for you.

My idle is high and can't get it to get back to around 700rpms. i was driving home one night turned on my road then it started this problem of idleing high, never stops, when the car starts it idles around...


What kind of vehicle is it? Try the throttle position sensor if it has one. If it has a carburator the choke is probably not working properly and needs cleaned or rebuilt.

Just picked up and 85 Crown Vic with 69k miles on it. Starts right up, but idle is very high. It sat for over a year in a garage without running, but fired right up when jumped. Where can I fine tune-up...


This should be fuel injected. But it is throttle body and it is an early one. It has a choke coil mounted to the passenger side of the throttle body. It doesn't run a choke it just controls fast idle. It might be bad or unhooked. Check for power on this.

Resetting throttlebody on 1998 be jetta glx


you can reset it by removing negative battery terminal while leaving positive terminal connected . open driver side door get in close door , put key in ignition turn over key almost all the way but do not start . you should here the throttle body aligning itself . leave key in this position for 15 seconds , remove key connect negative terminal and the throttle body should be set . this has been called the chicken dance and it works fine . what this does is resets the computer , key note though if you are planning to get your car inspected it will not pass until you have drove the car for at least 300 miles . being that the computer has to go through and set everything . i learned the hard way . throttle body problems usually happen when removing old battery improperly/battery being drained/improperly or jump starting the car/improperly , make sure when removing battery that the positive terminal is removed first , jumping a battery negative terminal is always connected first on both vehicles .

High idle car lunges forward


If you have a high idle and lunging...that usually happens when there is a leak on the intake manifold side allowing more air to get in, then the computer senses the increase in air and adds more fuel. There in turn has to be one more failure in the system to allow the idle to run away, may be a tps sensor (throttle position sensor) or something down the line.

2004 BMW X5 4.4i Left lights on resulting in flat battery. Car was jump started from another vehicle (Ford Transit van). Everything fine for a few days. Now, intermittently the radio/sat nav goes haywire!...


sounds like your car has the multi function steering wheel, i know on the 7 and 5 series they come out of sync, im not sure why.
its about £75 to get plugged in at the dealers and they reprogram it, sometimes i have had the odd car with a damaged slip ring, it does all sorts of things, 1 in particular kept on beeping the horn,
i would say if u got 1 urs got upset when battery flat.
