im having some problems with my 90 hb with a 92 LS B18B1, it was running really strong then all of the sudden now it runs like ****! the idle now goes from 1-2 grand when warm, when you step on the gas the car doesnt go my car cant make it up hills when in 4th you have to go to 3rd if you floor it the car doesnt pick up untill about 4 grand. i have gave the car o full tune up cap rotor plugs wires ect i thought it might be gas but it cant be because when i start it up in the morning and dont let it warm up it runs like it did burns though all 4 gears then when it heats up it runs like **** again. i was thinking mabey fast idle thermal valve but i dont know i have messed with throttle position sensor but it doesnt help still has a slow reaction on the gas. IF ANYONE CAN HELP FIX LET ME KNOW WHAT YOU THINK

When I looked at his car it was throwin like 3 codes i don't remember what they were but i didn't even care cuz i don't know OBD0 codes. (If anyone has a chart of OBD0 codes could i please get them!) He said that he got rid of all of his codes, but he also unpluged his ECT switch so that he could run a wire from his battery then to a switch in his car and back out to the radiator fan. That's how it turns on and off now! Why he did this i do not know
