coolant temp sensor and iac codes. i corrected the iac code by fixing the splice and moving the a14 pin at the ecu to the a12 position. ive thought about gaskets and vaccum leaks but, would that really keep the engine from running? stuff like that ive ran into in the past just caused an engine light or maybe a higher, rougher idle. the only thing i havent checked on the engine is the map sensor, because i dont have a vaccum pump. i checked the tp sensor as described in the haynes manual. thanks for the feedback, keep em comin,!
