My 91 Camaro with a 305 engine with 126,000 miles has started to change the engine rpm's while cold. I checked the trouble codes and it came up with codes 22 & 32. Has anyone had to fix either of these problems before? This is the first time that I have had a problem with the throttle position sensor or the egr valve. Any advice or suggestions about these problems is greatly appreciated.

Thanks for your help.

code 22: low voltage at throttle postion sensor or fuel cutoff relaycircutopen orshorted to ground

code 32: fault in barometric pressure sensor circut or fault in exaust recirculation valve diagnostic switch or fault in electronic vacuum regulator valve.

id say your 22 is a bad or going bad TPS. and your 32 is a bad EGR or MAP sesor.
