I have a 94 Geo Prizm LSI. Car cut on me on freeway. Popped hood and the single pipe connected to the exhaust manifold was glowing. Car would crank just not turn over. Replaced cap n rotor, spark plugs, ignition coil, coolant temp sensor, both o2 sensors. Car now starts just stalls at red lights or in park. While driving, check engine light briefly comes on and idle drops a little.
Thank you for your time, Jim
