Today I suddenly have a problem with my '98 CTSC
Description: when gooing through a right corner in 3rd gear, in the corner I started to accellerate almost full throttle full boost and suddenly the engine lost some power, a bit rough and both CEL and right after this TCS warning lights came on and stayed on.
The engine was running on 5 cilinders.
I stopped, turned off the ignition, waited a short while and started again: engine running on 5 cil, CEL on, TCS off, revved a bit and TCS came on again, turned ignition off again.
Inspected the engine bay for a few minutes, couldn't see anything wrong and no funny smells, so started engine again: CEL still on, TSC off and engine running bit rough but 6 cil again. Disconnected the battery, connected again, started the engine and all was OK, running normal and no lights, drove another 10 Mls and no probs.
After parking for about 6 hours, drove for 12-15 Mls and no probs.
Car standing for 3 hours and drove off again, after about 18 Mls, made another fast right corner, accelerated same as before and again same happend as before: the engine lost some power, a bit rough and both CEL and right after this TCS warning lights came on and stayed on, engine running on 5 cilinders.
Stopped, waited 1 or 2 min, started again but CEL+TCS and 5 cil.
As I was close to home, I quietly drove home running on 5 cil, stopped and pulled CEL: code 73, random misfire, misfire cil 3.
Connected OBD code reader and it says 2 codes: P1203 and P1303 Misfire cil 3.
What can be wrong???
