VIPSA

My car had some major hesitation problems so i replaced the air and fuel filter(used MANN 10x to Mance for providing us with the flow charts) and used Bosch fuel filter. I drove it and i noticed major improvement but still have some trouble between shifts 1st&2nd ( i still need to do the plugs cables and O2 sensors) but decided to add some fuel injector cleaner. After about 40,50 miles i got about 3 CEL's. Still haven't pulled them but I'm pretty sure they're gonna be lean bank 1&2.

I only use jectron from BLAU

I'm sure it's not the injector cleaner that throws CEL, there gotta be something else behind it.

That type cleaner can ash-foul the spark plugs badly. Happened to me.

without problems. Based on my experience with crappy California gasoline forumulations, I would rate BG 44k as #1 if you have serious carbon deposits and/or fuel injection problems (i.e., you have a problem, you saw it coming, and you did nothing about it until it got ugly), Lubromoly products as "suspect" maintenance products (i.e., you suspect a problem but do not know for sure); MMO, BG 3000mi, and Valvoline Supersyn as preventative maintenance products (i.e., use them before every oil change or other interval even if you do not have a problem).

As for STP, I got CEL's from that crap also, even running it straight through one tank of fuel (300+ miles high-speed desert driving non-stop Ventura Co. to Las Vegas). Stay away!

I've used Chevron Techron injector cleaner and a couple gallons of toluene with success

I wouldn't use bosch +4, just use a regular bosch platinum.

And I never have any engine problem with all my cars , ever.

They did not perform well in my 12v. The OEM NGK tri-electrode plugs were much better.
