injector flow
 

earlier this year, I had to directly apply 12 volts to my injectors to get them unstuck. I put them back in the car, ran some injector cleaner through, and have been driving for 7 months. I just had them checked for spray pattern and flow rates, and found there was only a 4% discrepancy between the injectors! Thats pretty cool saying as the shop testing them would have only got them within 5% of each other if there had been a flow problem.

Keep using injector cleaner and they'll stay clean forever.

I use a product called BG44K. I use this only once or twice a year as it's very powerful stuff. It's also expensive (about $24 a can). Try this in your car and you will feel the difference within 15 miles - it's great stuff.

During the rest of the year, I use Redline.

So far ive had good luck with Lubro Moly Jectron fuel injection cleaner (my intake valves are pretty clean too), but ill have to try the redline stuff for sure :)

Probably any injector cleaner will keep them clean. I highly reccomend the BG44k but only on ocasion. My mechanic told me not to use it more than twice a year as it is very strong. You can tell it's working almost immediately as the engine starts to purr and run very smooth.

Sounds intriguing...
