Re: 2004 Chevy Blazer Fuel Injectors
That is a hard one to call.
Cleaning will not help on injector circuit or restiance.
Injector restiance on room tempt is 11-14.
The code 200 is fuel injector control circuit.
Could be open circuit or voltage problem.
Always check the injector plug in.
And for injector pulse on that cylinder that has the miss.
Confirm good proper fuel pressure 60/66 lbs.
Is it a dead miss all of the time or just a ramdom miss?
