Re: EFI Tracker: ticking noise @ cold start, fixed!
The problem with those "injector cleaners" is they loosen up carbon chunks. They move around, fouling plugs, getting stuck under valves etc.
Pouring water down or some kind of chemical is about the same, just even more dangerous. DON'T!!!!
The so-called "injector cleaners - many of them -- the ones that add their chemical into the intake manifold -- think about it - it's a scam!!! How can it clean the inside of the injector when it never went through the injector?
The only real ones disconnect the fuel line and run the chemical through the lines and injectors! But those are dangerous! They attempt to clean it all in a few minutes - obviously the chemical is very aggressive. It loosens the big chunks - then they move around. And, even if the chunks don't come off right then, they do later, giving troubles.
There's only 2 ways to clean it all up properly and safely:
1. One is disassemble it all and clean - too hard.
2. The other is simple, easy, effective.
Add a can or two of TECHRON to the fuel tank. Use it double or triple strength to whatever the can says. It'll SLOWLY, SAFELY dissolve the carbon and varnish - then let it burn. It won't break off chunks - just dissolves it slowly. It'll be clean inside by the time you burn that tankful of fuel with the Techron. After you finish that tank, change the oil and filter!
There's alot of snake oil cleaners around, the best I've found is Techron or GM Carbon-X if you can find it.
