anyone recommend which product to use for this? car barely failed emission ... tech suggested I do this.

I read up on dirty injectors and saw how it slows down startup time ... my car cranks several times before starting, and I don't remember ever running these cleaners through my gas tank before.

any suggestions?

 

Clean the TB and the IACV, run a bottle of Techron in about 10 gallons of fuel.

 

Lucas Fuel Injector cleaner....also, have you tried running Seafoam through your brake booster line?

 

I've used both Techron and Lucas, but I think the Techron worked better, it's also more expensive.

 

ever notice a difference in the driving after running it?? 200k miles ... don't think it's ever had fuel injection cleaning.

 

I don't have quite that many miles (only ~57K right now) but I noticed a difference after I ran some Techron through...instead of cranking ~2 times before starting it tends to start right as you turn the key

 

awesome ... mine takes forever to crank and i've done every other maintenance

 

bought two bottles of techron 12oz ... poured one in today. Will probably pour again right before my next fill up. I'll fill up to about 10-12gallons as suggested here and on the directions.

This way, hopefully 2 cleanings will do the trick and get me to pass.
