well I dont know that car, but if you know where the camshaft is (middle of the engine) look where the front cam gear is. Its got to pick up a signal from the gear/magnet.
It sounds like your idle control valve is sticking. The video shows you where they are located on a 97 Buick but it is the same engine.
This video shows you how to replace them.
You mean 4,000 rpm . No engine goes 40,000 rpm . senor on the transmission that control the rpm. No SENSOR on the transmission ! Crank sensor's Take it to someone who has a tool like in the video an knows what he is looking at .
Ignition Scan data
I would suggest having the vehicle put on a scanner and monitor the operating parameters of the sensor for heater signal operation and sensor performance. You may not have overlooked anything. However, without knowing what the sensor is actually doing nand reading, you will be chasing your tail
Find the radio station you would like to store. Then press and hold down the button you wish to assign to that station until you hear a BEEP. That station will then be stored to that button.
Check the battery,have a load test done on the battery,now,it could be that the battery terminals,and battery cable ends are corroded,clean them really good,shining clean,this makes a big difference.Good idea to have the alternator checked also,while on the vehicle running,with the head lights on,and high blower motor,it should read at the battery,13.65 volts,to 14.25 volts.
If you follow up the brake pedal towards the steering column, you will see the switch.The switch can be at the front of the pedal or at the back of the pedal. It's not a difficult replacement, it's just hard to lay on your back in that small space and do the job. The part costs about $10.00. The question I have is why are you looking to replace? The faults are usually brake lights stay on which will kill your battery , or switch is bad and brake lights don't come on when pedal is depressed. I would first check for blown fuses, and blown bulbs. If you need any additional help please get back to me. GOOD LUCK FREIND.
you should ask the buick 4S shop to check the component model of your fuel filter, not just a size! or you can use a diagnostic tool like Multi cardiag M8 this to scan the model by yourself
By the info that you gave, I would have to say (guess) that it would be your wifes headlight switch. Because it is possible for the headlights to still work when the switch goes. The headlights, taillights, dash lights, dome light, and dimmer all work off the headlight switch and only part of the switch can go and the other part still be good and functioning. Hope this helps or at least, head you in the right direction to solve the issue. Best wishes.
CHECK THAT THE LINKAGE ON THE TRANSMISSION ISNT HUNG UP. OR HAVE THE TRANSMISSION FLUID CHECKED. MAY NEED A TRANSMISSION SERVICE DUE TO A PLUGGED FILTER.
