You are going to have to check the codes.Then we will know what the engine is asking for.
A code reader can be bought at Canadian Tire for $30 to $40.

check fuel pressure and check exhaust for leaks. exhaust leaks caqn play with the o2 sensor readings

Try this disconnect the heater hoses from the heater core use a hose to backflush the core. Then reconnect and try again.

The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???

Sounds like the catalytic converter or muffler are clogged. There isn't much exhaust at idle, but when you accelerate your exhaust volume increases, thus if your catalytic converter or muffler are clogged the restrict the exhaust escaping out thus causing an excess of back pressure which won't allow the engine to breathe normally.

My 1998 Jeep Wrangler has been one problem after another since I got it, but the effect temperature has on it is the second most infuriating. The worst is that it EATS starters... If anyone can let me know how to find recalls of some use, let me know (the guy above too).
