Getting codes 12, 22 on theKoeo test. MAP sensor out of range. At startup, it wants to die when at operating temp(idle dips to 400rmp's) Starts perfect cold.

From that list..... looks like you have codes 67 - separator(1) - 11 (system pass).....code 12 is not a valid KOEO code....... code 67 is not a problem since you were able to run a KOER...... code 67 may have been logged if the transmission was not in-neutral and the KOEO was run. Codes 44 & 94 are normal, or the equivalent to a system pass due to emission parts delete you did.

Its gone now, had it in nuetral[&:]Now, im getting codes 22(Map/Bp Sensor out of range)Also, Im getting a 12, but I think its an 11 on the KOEO test. I know my intake hoses could be changed, so don't know If ishould do MAP hose and other intake hoses and intake gasket or get a new MAP sensor. What do guys think the cause of code 22 is?

If the codes output is....... /-/-/-/-/-//-//-//-// .....11 - separator - 22.... clear codes (disconnect battery for 15 min.) and rerun KOEO.

I'll do that, the code output was 12,22,12,2 of the 3 times a ran the KOER. I know 2 is invalid, so probally was 11(pass).

Is your setup speed density or MAF?

Make sure the vacuum hose to the MAP is not collapsing or has a vacuum leak.... also make sure the intake port the MAP hose goes connected to, is not clogged. Suggest to do a Base Idle Reset Procedure after you clean the TB with carb cleaner and a nylon brush. LUK
