I just recently bought an 88 K5, i put a 4" suspension and running 35 BFG M/T's. I got a 350 TBI, 700R that is weak, 342 gears that are not enough and a warn winch up front. ITs a very good lookin blazer but needs more power and money put into it. Im havin some problems that I was wanting to see if someone out there could help me out with. Im getting an intermittent code for the throttle position sensor showing low voltage, the problem comes and it goes its not all the time and i replaced the sensor about a month ago so i dont know if i bought a bad one or if it caused by something else? Another problem is it likes to run hot, I do alot of driving on the interstate and after about an hour the thermostat reads way over the 210 mark. Any kind of advice on the problems or just on my K5 would be appreciated. thank ya the new guy from TN.
