I was wondering ..
Under Full throttle where does your L.E.D. read mine is usually right on the R or I on the rich printing on the guage
Is this thing even close to being right ?
with it being so far on the rich side do i have too much fuel going in ?
One other thing Black smoke is a sign of running rich also?i alos have black carbon on my exhaust tips that a sign of running rich ?
thanks

Funny that you mention the exhaust tips. I got mine put on 3 weeks ago and just 2 days ago a guy at work got the exact same tips on his V6 Dakota and his already have a layer of black stuff in them and mine are perfectly clean. What does it mean?

 

your injectors could be cloged up. run some cleaner through your fuel and see if it goes away. my truck had some build up on the exit tail pipe, and cleaning the injectors helped. the only reason i say this is because my dad noticed it and told me what to do.

 

my trucks has 10000 Kms on it I doubt that the injectors are fouled up?
or could they be i doubt it
plus the trucks never seen anything less the sunco 94 oct if that counts for anything

 

its worth a try
