KOER... no flashing

Key On Engine Running diagnostics: Theory says it flashes a 4 (number of cylinders divided by 2) and then an 11 (system OK). Then it does the EGR diagnostic, which makes the engine drop RPM and speed back up.

If you got a code 67 with the Key On, Engine Off diagnostics, the Key On, Engine Running diagostic will not run.

Code 67 - clutch not depressed (5 speed) or car not in neutral or park (auto) or A/C in On position when codes where dumped. Possible neutral safety switch or wiring problem. This code may prevent you from running the Key On Engine On tests. You can generally ignore this code, since it has no effect on engine performance.

The computer wants to make sure the A/C is off due to the added load on the engine for the engine running tests. It also checks to see that the transmission is in Neutral and the clutch depressed (T5, T56, Tremec 3550 & TKO)). This prevents the car from being driven while the computer is in test mode. Key On Engine Running test mode takes the throttle control away from the driver for several tests. This could prove hazardous if the computer was jumpered into test mode and then driven.

The NSS code 67 can be bypassed for testing. You will need to temporarily ground computer pin 30 to the chassis.

do not touch the gas pedal. My reader automatically revs the engine.

The simplest place is right at the computer. A safety pin to probe the wire from the back of the computer connetor is needed. Connecting it to a short jumper wire and grounding it should do the trick.
