Bad Idle and Hard Hot Start Problem 700 1989

Welp, take a look at (http://www.brickboard.com/FAQ/700-900/HotStartProblemQuickReferenceGuide.htm) as well as the greater (http://www.brickboard.com/FAQ/700-900/).

You can damage the AMM (or MAF) sensor by unplugging/plugging with the engine running. Possibly the fuel control system computer, too.

Air (vacuum) intake leaks?

Faulty engine control systems coolant temp sensor.

Fuel pressure regulator leaking fuel into the air intake port (manifold).

Also, PLEASE (http://www.brickboard.com/FAQ/700-900/EngineOBDCodes.htm)! Check them codes!!!!!

The 700-900 air box also has a flap valve that controls whether air intake comes in fresh of off the exhaust manifold pre-heater intake as controlled by a sping loaded thermostat. At least disconnect the pre-heater solder accordion hose from that shroud pre-heater plate on the exhaust manifold.

Clogged fuel filter. faulty injector relay, fuses, weak fuel pump(s), leaking injectors ... and on and on. Search the brickboard. Check them OBD codes and report back!!!!

Kitties are SO DAMMM FUZZY!!!!!!

Keep cool!
