Hi everyone: I am driving a 1992 Silverado. Every time I start from a dead stop my truck "grabs" as I press down on the accelerator pedal. It is like the driveshaft has a little too much play and "grabs" the rear end gears. I hope you all can understand what I am trying to write here. In the 80s I used to drive an older Scottsdale and I seem to remember the same thing happening: Cant remember if dad ever did anything to fix it, so I cannot comment furhter there. Also, after I drive for a few miles and the truck is up to normal operating temp it idles low - right at 400 RPMs. That seems a little low to me. Is there an easy way to adjust the idle? Today, I am runnig over and getting a Hayne's manual - I like it for the troubleshooting section. And, it has a little miss as it sits idling (possibly new plugs and wires). I am thinking of taking it to Sears for a fuel system clean: I used to work at a Sears, and I have seen cars respond and run much better after this procedure. The temp gauge does not work. Everything - and I mean everything - has been checked except for the actual gauge itself. New sensor, wires checked and OK'd, etc. I think the dash is one of those you just 'unplug': Should I look there (dash panel) and, if so, what am I looking for? Has anyone else here had this problem? Thanks for taking the time to read this. Any suggestions would be and are highly appreciated.
