okay i have an idle issue i do an idle relearn and the car runs good for a few starts and then on an odd number of starts it idles really high like 1000 rpms in drive and like 1500 in park

 

i believe it is electrical problem

 

 

i have changed :

intake manifold gaskets

i.a.c

t.p.s

i.a.t

all vacuum lines around the engine

fuel injectors

coil packs and module

spark plugs and wires

02 sensor

cleaned the plenum and throttle body plus the egr

ecm is good

 

 

okay ppl. i believe that is all i have changed so i believe it is electrical so if you have an idea or something let me know

 

 

thanks

Jeremy
