Goes in reverse and forward I've been told its the transmission, transmission sensor, and catalyic converter....?

It got bent putting the intake back on and now it's leaking. It is not the pressure valve. What is it called and do I really need it

At higheay speed sometimes the car will "shutter" and the tac will drop to zero. Sometimes nothing else will happen, sometimes it will try to stall and I will have to work the accelerator to keep it from stalling. During that "rough running" period the engine will heat up. Once I get through the rough period the engine cools off but the tac doesn't come back. If it DOES stall, it usually takes 20-30 trys to get it started again. But sometimes it will start right up.

diagnostic codes : P0102
this is my very first car in life and I'm 46yrs old. I bought it from an auction. I am very happy and proud of myself for finally being a car owner. please help me understand what I need to do and if I can afford to save the car.

I changed the window motor, regulator and switch on drivers side door. The passenger side switch works, a little slow, but does its job. Using drivers side switch, rolling both passenger and drivers side up or down doesn't always work. It works the first few tries but then quits. Then if you wait a few minutes it will work a few tries again... The cycle continues. So is it a wiring problem or what, where do I look or what are the next steps?

We charged the battery and after putting it back, it won't start due to the message about the anti theft device. Help!

My driver side window moves very slowly when going up or down. Can the motor itself be fixed or replaced?

I'm due for changing the battery out and would like to know.

The light only comes on when I first start up, then goes off, but sometimes comes back on after I've driven for over 30 minutes.

My car shows the ABS braking light is on, but I didn't notice any change in the performance of my brakes. Could it be an electronics problem?

The dashboard indicates to service tire pressure monitor. I checked my tires and the pressure is normal (~30 psi).

Even though my brakes are working fine, it always indicates I have low braking fluid when I make turns.

It doesn't stall every time I put in reverse but every so often it does. Car is an automatic and starts right back up with no problems when it does stall

Vehicle has ALL original parts from the manufacturer

It starts to vibrate when I stop at a light, stop sign, or in traffic and the car is in drive. If I switch to neutral is goes away!

Never done this before could hear like suctioned air when pushed brake peddle

I have checked fuses but they are fine.

Again I need to know what it is and how I fix.it

diagnostic code says code 42

When I am driving the speedometer will drop to 0 and times the the transmission will seem like it in nutreul. I have replaced the speed sensor and the range sensor and the instrument cluster in the dash and still have the same problem. Any help would be appreciated.

I recently had my secondary air pump and both check valves replaced to get an inspection. The car ran good no engine light. now after an Oil change my engine light is back on and my gas mileage is very poor, it reduced drastically. any idea on what the issue could be?

Switched out some of the fuses,they were still good though.Please help.

I have a 2001 Pontiac grand Prix. The key was getting old and started falling apart. One day the whole rubber insert fell out and I can't find it. My car won't start without that insert which has a computer chip in it.

My car has around 170k miles on it and I came home from work one night and parked and when I got up the next morning I had a puddle of oil under the front of my car and I even had oil that ran all along the exhaust. After sitting it quit leaking. I change the filter and there wasn't a double gasket, added more oil and it ran fine for a while and then started leaking again. It doesn't leak when it's shut off. It only leaks after running. Any ideas? I can't really see where the oil is coming from but it's somewhere the front passenger side.

At first it would click when i turned the wheel to the right side an someone told me it might be your axel. Then check it the boot is torn. Next few days it got to grinding a lil went to a brake shop the told me all my brakes are fine. So I'm wondering is it my axel making that noise? Or somthing completely different

I'm trying to get a key fob and idk if it already has the internals or not.

i took a 120 mile round trip yesterday and today it started putting pretty bad and it felt like it didnt want to accelerate well and when i came to a stop the car died and when i turned it over it has spark and power it just wont start very well

Does the brain to the car have to be reset?

replaced mass air flow filter now car wont start
