Rough idle dies, at 65 hesitation

My car has 198670 miles.
My car has an automatic transmission.

Hello. Thanks for writing in about your 2002 Chevrolet Silverado. This can be caused by a number of things. Most of the time this will cause a Check Engine Light to come on if there is a powertrain issue. If the Check Engine Light is on, then the computer needs to be scanned for codes first.

If there are any codes, it can help guide me to the right diagnosis. If the Check Engine Light is not coming on, then it may be a fuel system issue. From what you are explaining, it sounds like you may have a weak fuel pump or a dirty fuel filter. The fuel pressure would need to be tested to verify if these are the issues. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the hesitation issue.

Q: I am looking for torque specs on front upper and lower strut bolts as well as sway bar linkage nut, not tie rod.

Usually these bolts can be tightened very snugly by hand and be just fine. Almost as tight as you can but not quite. If you do not have the feel for this particular tightening method, the torque specs are likely...

Q: Power window will not open or close

When this happens, it's usually caused by switch or motor failure. In most cases, the door panel must come off in order to test it. I would suggest having a certified mechanic, like one from YourMechanic, run an inspection on...
