ok CEL came on tonight
throwing code 43

Ign. Coil circuit #1, 2, 3, 4, 5

all of those are the same code...

plugs have been replaced with bosch plat.4
rotor and dist. cap replaced last oil change, about 2K miles
wires replaced awhile ago maybe 8 oil changes?

tomorrow i plan to take off all the wires, cap and rotor and check for damage, same with the plugs..

is there anything obvious that im missing here?? or has anyone else had a problem with this??

ALSO
would unplugging the neg. bat. cable for like 10 mins. re-set the PCM and clear the code??
cause i want to clear is and see if it happens again after i check everything

any help would be GREATLY appreciated since this is my DD to school and work

thanks alot.

 

forgot to mention
the truck starts, dips dot to about 240-250 rpm then runs like normal...

i ran it 35 miles on the freeway today from 85-105 mph and everything seemed normal..

 

resetting pcm is accomplished on my 01 by disconnecting neg, battery and turning key to start for 30 sec. this should clear all codes and cel.

 

yeah i remember reading that somewhere in here

now to figure out my problem...

hmm..


i hope its just a loose spark plug boot..

 

Don't know if it'll make a huge difference, but check the TSB for the 98 rams about spark plug wire rerouting and try toroute them that way:

hmm i might do that if i have to tear everything apart

anyone else have any ideas???

 

the coil it self ...

 

my vote is : replace the coil

 

ok this morning before i headed off to class i made sure all the plugs were tight and the boots and connectors were snug, pulled of the ign. plug and blew some crap off it.

re-set the PCM, no CEL, been about 15 start-ups..

if it comes back on i will test the coil as it will probably need to be replaced, i do not think it has ever been replaced.
MSD coil will replace it unless anyone has a better suggestion?
