28 Vat sensor out of Range 27 ?? 14 Two or more successive erratic Profile Ignition Pickup (PIP) pulses occurred, resulting in a possible engine miss or stall. 41 HEGO sensor circuit indicates system lean 42 HEGO sensor circuit indicates system rich looks like 14 is the problem the Vat code maybe it was cold out at 32F it should read 5800 ohms and at 185F it should read 300ohms the O2 codes maybe by products of the engine miss or old codes from before you changed the O2 sensor.

I agree, looks like the pip in the distributor is failing.

The VAT, ECT, and ACT sensors will all throw an Out of Range code if the sensor is below 50 degrees when you run the KOEO test. Changing the PIP in the distributor requires a press to get the gear on and off. If it were my car I would either get a new PIP put in or get a rebuilt distributor from www.rockauto.com.

Gotta fix all known problems before diagnosing "new" problems.

What do you mean by "checked coil has power in and out of it but no spark out of the distributor."
By power do you mean voltage or spark?

Check to see if the rotor in the dist is turning?
