I own a 1994 dodge ram pickup,6 cyl w/200,000 miles on it. i bought it in 2001 and never gave it a tune up....

Question

lately its been hesitating and sometimes doesnt start right away. i used STP fuel injector cleaner when i filled up a month ago, and it ran great, but its doing it again. is there anything stronger than STP?

Answer 1

well you should use the stp fuel injection cleaner again then use the stp fuel injection treatment every other tank. This will prevent gunk from building up in the injectors.

If you have the money for a tune up, then by all means, do a tune up.

Answer 2

give it a tune up-fresh oil-new plugs and wires-an air filter. not meaning to be mean but...Hello?

Answer 3

you need to check the plugs in it id say they are in need of being changed,that alone will cause one to hesitate real bad, try changing those and see if that helps it adding chemicals to the gas wont make it run better if the plugs are worn out in it,good luck on it.
