Question about GMC Sierra 2500

1 Answer

My 1999 gmc 2500 pick up dies when you take your foot off the gas. Doesn't matter if your in park or driving down the highway. The truck has 225,000 miles on it but is very well maintained. Any ideas will help. Thank you.

Are there any codes,check engine light?The idle air control is the most likely problem here,not to high in cost,but most likely the cause for this.I hope this is helpful,If so,let us know,thank you.

Car died while driving down the highway


Needs tuning. Also replace fuel and air filters. If that doesn't help then it may need piston ring replacement.

you either have air in the brake lines, a cracked brake line, or low of brake fluid... either way you will need to bleed the brakes
