I have a 1996 Chevrolet pickup with a 4.3 liter engine and the problem is that the code came up as multi miss fire and low pressure regulator so I changed the plugs, wires, cap, roter and it still runs rough.
The engine light goes on and off so is there a web site that I can go to in order to find out the location of the regulator?
The regulators going out on the 4.3 liters is definitely a common problem. I would recommend not just replacing the regulator but replacing the whole spider injector...the whole set-up… the whole kit and caboodle! This repair will set your bank account back a little being as it is a high dollar fix, but afterwards it will save you from getting gas into your oil and of course ruining your motor. I would recommend trying to find an aftermarket one to save you a little dough, take a gander at “Parts.com”
Thanks for reading!
