I changed temperature sensor, put new air filter and air cleaner gaskets (there were not any
), and things looks much much better. The engine runs almost normal, starts much easier and there is no this black smoke out of exhaust
Thanks a lot for the help
Next step is to change distributor cap and rotor, spark plugs and wires.
I have some additional questions. Since I am going to disassemble and clean TBI, is it good idea to change injectors as well?
This one looks good deal:
GM THROTTLE BODY TBI FUEL INJECTOR SET 1987-1996 5.7 V8 GMC CHEVROLET PICKUP VAN | eBay
What do you think?
Thanks for the help,
