#72028 OBD1 cars only have 1 O2 sensor. It's not until 96+ that you have a second O2 sensor after the cat.

Bent valves will cause you more serious problems than just idle. What makes you think you have bent valves?! That's scary.

#72054 i have no cel...the guy i bought the car from(he buys broke cars and fixes them and sells them) said the he replaced the gaskets and all that but used all the same parts on the motor..the guy HE bought it from had a turbo and blew it like 3 times and then blew the motor the last time..thats why im wondering if i should just trash this motor and get something else..i dont know the condition of the internals..i could take it apart i guess

#72077 sounds like a headache... I'd try a basic tune up first (plugs, wires, cap, rotor) At least if you end up having to rebuild, you'll already have all that stuff for your fresh motor.
