Having problems with your 1988 Plymouth Horizon ?

My 1988 plymouth horizon runs fine when on throttle but when i let up it spits nd sputters and dies. I have checked the charging system and it brings up no codes.

Answers :

Check and clean AIS motor. (automatic idle speed) sometimes referred to as IAC as well. ( Idle Air control) same thing. remove it and clean pintle (pointed end) well with throttle body spray cleaner, as well as port it comes out of, and try it. If it's cured great, if it happens again a little later, replace it.
