More help please.
I put a new alternator in the car and the car is running now, however I am still having problems. Even before I put the new alternator in the car was bucking a little when I tried to accelerate or was going up a hill. Now, however, I am get an engine light. Every time I have the codes checked it comes up the same two codes. The car is misfiring in cylinder 4.
I have put Lucas injector cleaner in my tank and have changed spark plugs and ignition wires. I used auto-light double platinum plugs. And I'm still getting the same codes. What should I be looking for? Is it the injector or is there other possible causes? What are they and what do I do to fix the issues
