How's the cap and rotor?

 

and the plug wires/routing.....

 

cap rotor button wires plugs al new ive heard about the routing of the wiring but i really dont see why it have to be done

 

Plug wire routing TSB.

Reason for doing this is because the wires tend to 'cross talk', giving you misfires. Supposedly, with GOOD quality plug wires, it isn't absolutely necessary....

 

i guess these are the good wires they ran me 60 bucks

 

well i re routed the wires an it didnt seem like it changed an as for the drivetrain my transfer case blew in half lol

 

OOops. That would definitely be classified as a "problem".

 

a 400 dollar problem 300 for the transfer case had to put u joints on everything and have to have trani pan welded the driveshaft beat the hell outa it

 

The plenum gasket is blown and the cat is shot, as is the pre cat o2. It's a 98, trust me , I know.
