Having problems with your 1997 Chevrolet Blazer ?
My blazer has a misfire i think or is going in and out of gear between 17 hundred rpms and 21 hundred rpms if you hold steady between these you can watch the tach bounce and feel the misfire past this though it seems to run fine the speed is between 30mph and 45mph ive tried it in just third gear and in overdrive trying to fix this ihave replaced ciol wires plugs cap and rotor same thing iwas told possible speed sensor but im tired of throwing money at another guess
Check fuel pressure should be 55 to 65PSI. Check ball valves on the spider fuel injector. Disconnect one by one plastic tubes from engine block, and use Non Corrosive Brake Fluid (green can) to make sure that the holes are not clogged. Good luck.
