my waggy is pulsing at idle, when it does acts like its gunna cut off and runs rich as hell. but then it will clear up stop running rich and then will start again! what would be the first thing u look for?
 
I guess that woudl be an XJ waggie, dunno (the fullsize ones are technically granad wagoneers, but commonly called wagoneers also). If it is the XJ, it will be a Renix 4.0L with EGR. The EGR valves can be finicky, I'd see if the vacuum line to the EGR solenoid is leaking.
