My 2002 DII is idling at 2k rpm at startup then dying down to about 600 rpm once it warms up. Im getting codes for the Cam position sensor, TPS, MAF sensor, O2 sensors, two evap codes, and the M & S dash lights are blinking. I replaced the TPS last week, cleared the codes, and they all came right back. When I give it gas it bogs out and the rpms instantly drop. The coolant reservoir is also boiling after about 10 minutes of idling.
Does the 4.0L V8 have a temp sending unit or just a coolant temp sensor... where should I start from here?

 

Sometimes the M + S lights can be indicating a low battery output (anything below ~13A will cause the lights to go off, putting your tranny in limp mode). I would start by getting your battery tested (and replaced if needed) and seeing where that leaves you.

 

hey is fuse 2 engine compartment blown. its a 15 amp fuse.

m and s blinking could be the xyz switch out of synch. but that would be a 705 code.

 

I'm going to have to power probe the fuses to see if any are blown. The battery is brand new so that's definitely not the issue.

 

I had a brand new battery and still woudl get these flashing lights. I inspected the battery connecters and found a light coating inside one. I sanded it smoooth and got rid of the m&s lights. You probably made sure those were clean but just in case I thoguht I would mention it.
