I have a 1988 1/2 ton, 302, 4x4. I need a good injector cleaner that actually might make alittle difference. I have half a miss under load and the old dog's a bit sluggish. Plugs and wires didn't help. Maybe the next hottest plug above a stock plug might help? Any and all suggestions appreciated. Thanks.

 

Did you change your distributor cap and rotor?

 

Chevron with Techron is one of the best in-tank, shelf-brands you'll find. Leave the STP crap alone - it's a waste of money.

go to the dealership and say "do it" They will give it the most potent dose that can really be done. I have done it to my car and truck, and it is an incrediable diffrence.

 

try having someone (prof.) clean the injectors this if anything will make them like brand new i charge $100.00 and the difference it makes my customers are happy to pay it most service shops have this machine blow the bill and see how it does

 

Brand new injecors are $200, just a thought. Don't they reccomend replacing them at some point anyway? Its an '88 after all. This is of course if you dont mind replacing them yourself (its not a big deal). I have no reccomendations as far as in tank cleaners, I've used some, but never had any results that made me feel like I got anything other than peace of mind.

 

I'll second the Chevron w/techron!

 

I'd try beastie's recommendation first, cap and rotor. I recently tried that seafoam crap after reading posts in the engine section about it, and, it actually works pretty well. Only down side is it costs $5.00 a can!

 

Chrevron cleaneri s the way to go.
You may have to double up on the cleaner...two bottles should do the trick.
