Sounds as if you have a sticking wheel caliper, or the brake pedal itself is not returning all the way. Try pulling up on brake pedal. If this works, lube all pedal movement points. Otherwise, jack up front of car and see which wheel won't turn, and fix caliper.

Never heard of Hulk, but I always use AutoZone for recommended oil and fluids.. Try autoxone.com

it gets a high-temperature signal from the coolant temperature sensor,if the sensor is bad. it will not operate right. Current flows through the closed contacts of this switch to the electric motor, which spins to operate the fan. if the coolant level is ok, I would check the coolant temperature sensor and the fan relay in the fuse box. Good-Day!

probably a bad spark plug wire

Do any of the other buttons on the remote work, like the horn or trunk-open buttons? If they do, then you might have a blown fuse or relay switch for the specific problem. On my Grand Am, there are relays for "Door Lock", "Door Unlock" and "Driver Door Unlock".

remove the boot around the shifter and tighten the linkage bolts.

Reference the radio coding we can't help as this code always is given by the car manufacturer through the the car suppliers and always by giving the chassis number.

Only 2 and 3 injectors are firing on my Chevrolet optra,I checked and see that there is no injectors pulse on number 1 and 4 injector,can anyone help please

Every engine can... it happens when you try and restart the car... when the engine is running and the timing belt breaks everything is moving so it doesn't usually damage anything... when everything is stopped your piston slams into the valves and bends them. He'll of a big job

You need to go to a dealer, take the VIN code the number from the radio and most important of all proof of ownership, they have a number to call to get the code. I hope this helps. Take care.

There should be a radio code with the manuals in the glove box.

For auto transmissions with NO dip stick and filler tube in the engine bay, the fluid has to be pumped in by removing a filler plug on the side of the transmission. You must use the correct procedure for this so the transmission is not under or over filled and the vehicle needs to be perfectly level when doing this. It is best left to a professional. Take the car to a Chev dealer to have it done and get them to drain the old fluid from the transmission and refill.

Should be right beside the harmonic balancer on the front of the engine!

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few like reliable-store .. let me know if u need help thanks

Hi there:On your vehicle, the fuel filter is inside the tank and cannot be replaced seperatly.Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using Fixya, and have a nice day.

you might have a faulty stop sensor that is usually located on the brake pedal

i dont think so try using a different oil filter or higher octane gas
