It's most likely something that I've PG13ed with but would appreciate any suggestions.

I have removed the plugs and have spark at each plug as I wind it over and as above seem to have plenty of fuel.. so I'm thinking it's one of the sensors???

Thanks
Got a diagnostic light set up on it or do you need to plug into the ALDL to check for stored codes? If so, what code/s is it spitting out?

Usual basic stuff, check your earths, battery voltage, that you haven't connected a couple of sensor wires rrr's about or stuck a screw through a wiring harness etc etc. Was it black smoke (fuel)? You didn't have a rag on or get oil all over the distributor module (silver box usually but there are different brands about these days)? Clean throttle body/idle air control motor passage?

You might need to bump up the base idle screw a 1/4 turn or so to help "facilitate" the ECM learning process for the A/C for a couple of says running, then reset it back to specs afterwards.
