Prob i've seen with gas injector cleaners, is that they loosen up stuff in the tank and lines that then clog the injectors.... just something to think about

I've had a good experience with the BG ISC product on my old dd at 150K miles. There was an immediate difference in idle, throttle response and fuel (28mpg highway to 33mpg) economy. The plus, was the absence of secondary problems. The minus was the cost......
Personally, before I'd clean 'em, I'd just replace them with new Bosch units.

I used Berryman's Chem tool and after having fuel pump problems, I picked up a can at the auto pars store, and it has methyl-ethel ketone.
which melts plastic.
had starting issues, and fuel supply issues, and bouncing fuel pressure gauge needle at idle.
changed the pump and the car was fine

I use the Chevron Techron in my 89 and it appears to create improved engine performance........and I have non-stock Lucas injectors. I would not recommend that injector cleaner be placed in 89 -91 cars with stock injecectors. Just my $.02 for what its worth

IMO, the best thing you can do if you think you have an injector problem is to check each injector individually. On an LT1 it is very easy to remove the fuel rails with the injectors. Charge the fuel system and look for leaks on the injectors. Then using battery power and a long wire with a REMOTE switch fire the injector for a certain length of time while catching the gas in a can and compare the flow rate with the other injectors. If you find an injector not performing then you might want to replace it or try to clean it.
NOW DON'T DO SOMETHING STUPID AND BURN YOUR CAR UP AND YOUR GARAGE DOWN. Sparks and gas/fumes don't mix so use your head and you'll be alright. Remember safety first.

Just be sure and do it near your next scheduled oil change for maximum benefit. There's no sense in letting all that crud run down inside your crankcase, mix with your oil, then circulate throughout your engine.

I have a can of some 3M cleaner that attaches with a hose to the fuel rail. You take the fuse out for the fuel pump and run off of the can. I had a friend use it years ago and he said it worked great.

I've used 3M Port Injector Cleaner through the rail on a couple of GM's without any results - good or bad. My '97 S10 - when it started throwing P300's, was cleaned by the Dealer and that cleared the Code and stopped the misfire. GM has a special warranty on the injectors (regardless of type) on all '96 or '97 through '98 or 2000 in CA for 200,000 miles. A lot of injector problems have nothing to do with flow - ohm them out hot and cold first.
