Default Corvette EGR Control Valve Relay Solenoid

OK i never ever had to deal with a code 32..
OK a 32 code means erg frailer and that could mean? Corvette EGR Control Valve Relay Solenoid?

or what else could that code mean yes my maf was acting up as well but i fixed that and that was a diffident code ...
can some one give me a hand on this i'm kinda lost in the woods.
the funny thing thing is she runs great after worming up then it come back later if i try to run her to hard like shes looking for more air?
would the fuel injectors trip a code even know it not for them??

all so could this be the part that acting up hers a picture..

hers what the part states


* Replacement Solenoid * Bolt-On Installation * Corrects Stalling, Rough Idle, Engine Knock, Surging Or Hesitation Caused By An Inoperative Or Incorrectly Functioning Solenoid *Non-Returnable Electrical Item The EGR (exhaust gas recirculation) system in its most simple terms is meant to reduce smog. The system reintroduces spent exhaust gases back into the combustion chamber to reduce oxides of nitrogen. The EGR valve on 1985-90 Corvettes is opened and closed by the EGR Control Valve Relay Solenoid (that's what GM calls it). This part is also commonly referred to as the EGR Relay, EGR Solenoid and EGR Switch. The solenoid fails at a much higher rate than the EGR valve and typically causes your C4 Corvette to stall, experience rough idle, engine knock and surging or hesitation during acceleration. Before replacing the solenoid be sure and remove the EGR valve and make sure there are no carbon deposits on the valve itself. If it is clean or if you clean off the deposits then it is generally safe to assume your Corvette's problem is the EGR solenoid. If you have a scan tool and you read a code 32 then it is letting you know you have an EGR system failure. Further vacuum and electrical testing at this point can definitively I.D. the switch as the culprit. Should you be unsure of the diagnosis it is suggested you visit a professional mechanic as the solenoid is a non-returnable electrical item. Corvette Central #: 304115 Original GM #: 1997195 Car years: 1986, 1987, 1988, 1989, 1990, 1991


i just don't want to buy the wrong erg relay if that's the problem..

The EGR temp switch is likely. Follow the diagnostics and you will find your answer.
