For those who are experiencing high/surging idle, hard starting when hot, and pinging you really need to investigate air leaks in the intake system. This is a known issue with the 1700, and may well be amplified by Ivan's flash.
There are 4 places it can leak, most common is between the throttle body and manifold (Thunder makes a gasket for this), the two little rubber plugs on top of the throttle body could be cracked, the rubber seals at the injectors could leak, and the seals between the manifold and heads can leak. I had high idle, hard starting when hot and pinging when I first installed Ivan's flash but after disassembling everything, adding the gasket, replacing the plugs and injector seals, and I used Hylomar to seal the manifold to the heads...... all those symptoms disappeared. Continuing to run your engine with an intake air leak can cause expensive repairs down the road, mainly burned valves and seats and other things resulting from overheating and pre ignition.
