I just recently put in a junkyard motor a while back and now im having issues with it not idling correctly and a lag in acceleration
have codes that pop up
leading me to believe its either a pcm or coilpack... i believe
the codes are as followed 1620 low coolant circuit.... (has a new coolant sensor and wiring...)
p0401 Egr insufficient detected.... (Newer egr and cleaned the passageways )
p1640 quad driver module a malfunction that was on before i put the junkyard motor in....
p1599 engine stall or near stall detected (does feel like it wants to die when sitting at a light.
p1641
p0326 knock sensor 1 circuit range performance bank one
please help
THANKS

 

oh my

Did all the wiring harnesses match up exactly after the transplant?

 

surprisingly yes

 

any help please?

 

sorry -- must admit I forgot about ya

need some sleep --- will get back over the weekend

 

The "1599" code is set because of the improper idle.

The "1620" code is for low coolant in the overflow tank. Probably a gummed up sensor

 

It has a new coolant sensor and wiring....
any ideas about the idle?

 

which coolant sensor is new? the one in he head or the one in the bottom of the reservoir? Reservoir sensor is one we're talking about here
