Will an advanced DTC reader help me with my e320 troubleshooting. (Idle problems)
I have a 1994 Mercedes e320 that used to have a surging idle/loss of power on acceleration problem that I had been "attempting" to fix. I say attempting because I was getting nowhere except to determine that I did have the updated wiring harness. Suddenly, out of the blue, and for no reason that I could determine, the car started running perfectly and ran this way for well over a year.
I had been getting excellent help on the forum, but I've decided to start a new post since so much water has gone under the bridge that I'd like to start out fresh and from a new angle.
I'm planning on focusing on the diagnostic codes (I have several) and was wondering if it is worth it to build the code reader that plugs into the module to give advanced codes. I have the 16 pin obd1 error code module.
Using the push button on the module I get the basic led flash codes. My codes are :
23 -intake manifold pressure (in base module pressure sensor- B5/2) with engine too low/high
26 -Upshift delay defective
6 -Idle speed control inoperative
3 -Lambda control inoperative
I'm assuming that some of these faults are related to each other. Would the advance reader help me sort things out or just cloud the issue?
Thanks for any advice. I've been having a bad year things being broken down and I'm getting behind on tying up my forum post. It seems like this car is going to be an all summer project.
