I just bought the car and after 2 weeks the I'm went bad. The only code that pulled up was bad mad sensor. I noticed the I'm looked like it was recently replaced and the coil tends to get hot the number 1

I need to replace my Cadillac converter in my 2001 Buick LeSabre.

Need price for parts and labor

I installed a stereo in my 2001 LeSabre,my car was running normal when they pulled into the garage. After we finished with the stereo we were going to start it to tune it and see how it sounded, my 01 lasabre wouldn't start. It turn over and sounds like its going to run but it won't engage. I have checked the fuses and put a battery charger on the battery and tested it and it's at 12.6 volts. Please any ideas/advice is appreciated. I don't know what's wrong if it's the car or the stereo? Can you help me?

We installed a Kenwood DDX-319 in the car. After we were finished we tried to start it, it turns over & sounds like it is gonna start but it wont. It has backfired a couple times when I try to start it again, it was running normal before this. Could I have done something installing the stereo to cause the car to do this? I have checked the fuses, the volts in the battery are normal, not sure what to look at next. It will not engage and stay running so I cant take it anywhere, Please any and all advice/ideas would be welcome as I am overthinking this and cant come up with anything!! Thanks in advance

my '94 got around 30 32 on highwy. so was expecting the same about. It runs great starts right up but the mileage is awful! what to do ???filters ? computer read out doesn't show anything check engine light is not on.Thanks for your help.

Anyone had any similar problems?

For example, i put the key in the ignition and it will not start unless i give it gas. I have even trued jumping it and still no effect? I have replaced the battery, alternator, MAP, MAF, IAC, and TPS sensors.

Check Charging system error. Test indicate bad battery and bad voltage regulator. However when jumped off other car with good battery the alternator IS producing and guage reads that it is charging... If started from car (bad) battery no charge is indicated.
Could the bad battery be causing the voltage regulator from kicking "in"?

In short, if I replace the battery is there a chance that alternator will work?

I filled the coolant box once before and noticed it was very low yesterday as I was running errands- filled it with water otherwise it would have overheated. Today I did a pressure test on it and it has an ongoing stream coming from a tube in the bottom of my car- can't find a diagram without buying a 30$ manual.. anyone have a diagram or know what tube this is?

Tach erratic, bounces at will but mostly rests at zero. Do not know what drives the tach, mechanical, electrical or vacuum but wonder if this is a precursor of future joy with my beloved Buick!

This vehicle doenst have dual climate control can this problem be diagnosed with a code reader?

.is it metal or aluminum and is it top or bottom
