I got a code for TPS and lean both banks. I change the TPS and that code has not come back up. I wonder if it could be plugs and wires making it hard to start and not enough spark and thus I am getting a gas build up in the cylinders.
Any other ideas.
TIA
Check for a vacuum leak. Also look at the top plenum gasket. I have seen them fall inside when being installed.

I did not remove the plenum.
The distributor has nothing to do with ignition timing.
1) Fuel pressure spec is 60-66 PSI That means you should have no less than 66 PSI KOEO, no less than 60 PSI KOER. 2) Clogged injectors (likely if you allowed the fuel to drain out of the injector assembly when you replaced the gaskets). 3) Distributor cap and rotor have to be Delco, no/none/zip/zilch/zero aftermarket brands work on this application
Look at it this weekend. Fuel pressure is OK
Codes I am getting are P0452, and P1335
P0452 - Evaporative Emission Control System Pressure Sensor Low Input
P1335 - Crankshaft Positioning Sensing Circuit
Could this be the distributor is one tooth off in any one direction?
NOPE. Crankshaft position sensor is not in the distributor. It is located in the front timing cover under the crankshaft.
The CAMshaft position sensor is in the distributor. However if the engine starts and runs and doesn't set a cam code then it is VERY close to correct. If it is off by one tooth either way you WILL set a cam code.
The 0452 code could be a bad tank sensor or a problem in the wiring. Not hard to test BUT the sensor is a PIA to get to with the tank installed.
I had the codes check today and it now shows two codes both the same P1345
