I have a 1992 b2600i 4x4. I've had idle issues for years. I cleaned the Mass Airflow Sensor and Throttle Body and Idle Air Control. Was throttle body cleaner okay on the IAC? Throttle body was filthy. Car ran great for a week, which it hadn't in 14 years but started back with the idle issue. (generally low, would stall in gear at idle) IAC gasket had broken apart in pieces. Dealer wanted over $30 for it so I made one out of gasket maker. Since that, idle is HORRIBLE, very high, up and down. I wondered if resetting the ECU is important and if so how to do it for my truck. I want to make sure I do it right if it is needed.btw, I did use carb cleaner on the MAF. Thanks!

 

I learned. Battery cable off for a few minutes. Hasn't helped though.

 

So...My car is 2003 Mazda 6 3.0L V6 S (AT).I have problem with ECU,ECU number is "ECU PCM Brain Computer Engine BDD3 AJ58 18881 G 3.0L V6 S ECM".The thing is that Ecu's one of the cheap/micro scheme burned,and because of this one of the cylindrs stopped working(but car is still running).My question is next:Is there any difference and if it is what difference is between 2.3L ECU's cheap and V6 3.0L cheap???Can I use 2.3L ecu cheap for V6 3.0L???
SORRY FOR MY BAD ENGLISH I HOPE YOU CATCH WHAT I SAID
