SOURCE: timing belt broke bent valves
Hi!!This occurs when the ignition timing and fuel mixture are changed causing an excessive amount of heat.
If the engine is running on a VERY lean or rich mixture, the temp will be so high to make the exhaust manifold glow red,. which would damage the catalytic converter making things worst.
You did not provide the vehicle's year and model, but, you should have DTCs stored in the PCM memory. Scan the computer for Trouble Codes and you'll find out if the mixture is in the lean or rich side and you can make the necessary adjustments. AutoZone, Checkers and similar auto parts stores let you borrow DTC Scanners.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.
If the timing belt broke..9 out of 10 time there was some type of internal valve or rod damage. The engine does not have enough compression to start or ignite the fuel vapor. Valves are not sealing correctly for combustion. Check with a compression gauge in one of the spark plug ports. It's a 96 and at this point may not be worth the problem to repair
