I have a 1995 GMC Sierra SL with the 4.3 Votec TBI and it runs great. Only thing is the check engine light comes on after ive been driving on the freeway for a while but it doesnt effect the running of the truck. Any ideas? Also my speedo wont work either. Ive replaced the speed sensor but it still continues to not read correctly or it just bonces around or stays at 0mph. Any help is deeply appreciated!
