Customer Question

Mike,
My 99 Silverado is having a hesitation problem when accelerating, no codes set. A problem occurred before, first time I solved it by replacing my K&N Filter with a paper filter, second time solved by cleaning & tightening all connections between the MAF sensor & throttle body. Cleaning MAF & tightening all connections is not helping this time.Are you available to consult on this Silverado problem today?BTW the O2 problem on the 97 Suburban did not return, and the HVAC switch replacement you helped me solve is doing great.

Hi Roy,
Prior to receiving notice that you replied yesterday, Monday Dec 21, but after sending my email I completed work on my Silverado for the day. During those hour I used a top engine cleaner on and through the throttle body, and I also changed my fuel filter; then I drove the truck about 25 miles. So far I have not noticed any hesitation, and hope I solved the problemIf the problem reappears, going deeper into the fuel system would likely be appropriate. I'll follow up with you on how to check the fuel pressure.Thanks for your attempt, given the busy holiday season, I realize it does take time to coordinate conversations.
