ok heres the problem, the car has started showing different afrs after hitting 160 degrees and not running consistent afrs at all now it has started cutting ignition is my best guess because the car dies after 160 and if i hit the gas the uego just shows full rich, i pull over let the car cool for 5 min and it will start back up and run until 160 again???? i just replaced the tps it may be alittle out of adjustment i replaced the water temp sensor for the ecu and a new alt can anyone help me out?
thanks guys yall are life savers on this forum
