'97 D1 147,000 mi
TPS has 50k on it
magnecor wires have 50k on them
stepper motor has 50k on it

starts and runs fine until warm up
then misfires, chokes and is undrivable

code reader tells me:

P1316 MISFIRE EXCESSIVE EMISSIONS
P1317 ABS ROUGH ROAD LINE HIGH FAULT
P0300 MISFIRE MULTIPLE CYLINDERS
P0430 CATALYST EFFICIENCY LOW BANK A
P0420 CATALYST EFFICIENCY LOW BANK B
P0340 CAMSHAFT POSITION SENSOR ERROR

O2 sensors are original
MAF is original

any thoughts?

thanks in advance!

 

How mechanical are you? I would be glad to help you, if so, send me your tele number and I'll call you.

 

Ok, thanks Mike for hammering out some ideas over the phone.
I just put in a new camshaft position sensor, cleared the codes and took it out for a spin.
Ran fine for the first 10 minutes then started to sputter and lose power, top speed 28 MPH.
Checked the codes and got: 1316(misfire/emissions), 0300(misfire mult cyl), 1317(ABS), 0340(camshaft sensor error)

any more thoughts?

thanks

 

if the wire to the camshaft circuit is good then I bet when you pull out the ECU it will be bad. But at the same time the Crankshaft position sensor can cause the issue as they need each other to work properly.
If the crankshaft sensor don't work and the wires are good then most likely the ECU has bit the dust. Just buy a used one then go to the dealer and have them program the security. Don't swap over cause the vehicle will not start.
