Car stalls intermittently when shifting from Drive to Revers
I have a 2004 Bonneville with 57K on it, I've racked up about 36000 on the old Odometer since a bought her last April.
Since the first day I've owned the car, it has the tendency to intermittently stall when shifting from drive to reverse. Sometimes it would act like it wants to stall but then catches itself (RPM'* drop from 800 down to 3-400 rpm'* then recovers). Other times I can drive it for thousands of miles without it stalling once. I've had the MAF sensor replaced and the lower intake gaskets replaced during my last visit at the dealership. They figured that this would take care of the problem. (It didn't)
Any suggestions about where else I should be looking?
I thought about new plugs and wires but it did this when it had 21000 miles on it and it does it every once in a while ( I can count the number of times that it has happened to me on one hand). It'* just that I've never owned a vehicle that has had this issue and it'* annoying me.
I'd start with the Battery cables and grounds. Clean, apply dieelectric grease then reinstall.
then remove the ICM connector and do the same while tightening up on the connector sockets. Finally do the same for the intake sensors. Remove the IAC and clean it.
Let us know how it goes.
Ok I found it. These codes do not make much sense to me but I am sure a gearhead will chime in.
