misfire toyota celica and manifold got red hot
A red hot exhaust manifold means it's running very lean, possibly your 02 sensor has worn out, among other possibilities, including an air intake leak causing the fuel/air ratio to not adjust the fuel trim. It will also cause the misfire. Another possibility is a clogged catalytic convertor
When was your last tune up? Have you checked computer codes? Toyota OBD1 I doubt if any parts stores will be able to check them. Check the basics first, plugs,cap,rotor, wires, fuel filter, air filter. Then it gets more involved.
What kind of misfire was it? My 01 celica gt had a misfire in cylinder 4, checked all the spark plugs and they were pretty worn. went to autozone bought 4 ngk iridium spark plugs, spent 30 mins putting em in and now it runs smooth as butter
I got a 96 celica the manifold gets red hot . The engine was rebuilt . I changed the converter and still gets red hot. If I drive in the city is ok. But if I get on the highway hitting 60 mph for about 15 minutes that's when it gets red hot.
