Check Engine light with a system lean code
Check Engine light with a system lean code ok fellas I have tried a ton of stuff on this one and its about to really aggravate me with the diagnostics. I have cleanded the throttle body and ran an air induction cleaning service, replaced the fuel filter. when i cleaned the throttle body with the wire brush, the check engine ligh went off and then later 5o miles it came back on. its acts like it idles down at a stop and then its trying to choke out.. someone please give me some info and help me save my baby from detonating.

what is the Check engine light code? (probably a P0xxx (that's P zero)) may be a P1xxx (P1 means manufactuer specific) .... but regardless.... what's the code and we should be able to hlp 
usual reasons for a lean condition:
exhaust leak
if both sides then vacuum leak
injector failure
regulator failure
exhaust leak and injector failure are the most common
did this SES start soon after installin any mods?
How many miles on the car?
what kinda car?
need more info to help ya
