I have a 1990 RS camaro, Bottom end is a 350 bored .60, topend has 305 TBI, Car ran like a champ, but lately it started misfiring and gas mileage has gotten extremly poor. I'm getting a code 32, 44, Idle is alittle rough. I thought the problem was solved, when i noticed the knock sensor wasn't hooked up, and 1 of the lines were off the canister. The rpm guage is going crazy.

I hooked knocked sensor back up and canister vacuum, Gas mileage went back to normal and misfiring stopped for 3 weeks, now it's doing the samething, but the knock sensor and vacuum hasn't come loose, any idea's would be most appreciated.

 

 

Yeah, I did that when i hooked them back up. afterwhile Code 32,44 always came back.

 

I had did that, after i hooked both of them back up, like i said weeks later it started back. I replaced theI GNITION CONTROL MODULE, today. Going to see what that does, only paid 3 bucks for it..

 

Was the tach reading erratically when the problem happened again? If so, replacing the module may solve the problem.

 

yeah the tach needle was going crazy, so far no prob. except Check engine light on for Code 32, gas mileage still looks to be poor.

Code 32 - BARO Circuit Low - Barometric Pressure Sensor Circuit Low.


Code 32¥ - EGR - Vacuum switch shorted to ground on startup, switch
not closed after the ECM has commanded the EGR for a specific
period of time or the EGR solenoid circuit is open for a specific
period of time. Replace EGR Valve.
