Do you get a code 32 on your V6 Fiero? It usually occurs at highway speed, not always at idle, and may come and go as you drive. Normally this is due to a malfunctioning EGR Vacuum Control Solenoid which is located right under the map sensor on the passenger side of the engine. This Solenoid has a total of 3 ports, one dual rubber line port (vacuum source/EGR valve), a fresh air intake port, and a 4 pronged electrical connector. This controller is activated by the ECM when the input from the coolant sensor, MAP sensor and engine RPM are within normal operating range. With this input the controller then supplies vacuum to the EGR valve diaphragm (the valve on the drivers side of the engine above the exhaust "Y" pipe). This allows exhaust gases to flow up the EGR tube to the intake plenum to actually "cool" the piston chambers. If this system is not operating to factory specifications, too little or no EGR flow allows combustion temperatures to get too high during acceleration and load conditions. This could cause: Spark Knock Engine overheating Engine stops after cold start Engine stops at idle after deceleration Car surges during cruise Rough idle The Fix? If no vacuum leak is present in your EGR circuit and your EGR valve is functional, replace the EGR solenoid.
This solenoid is GM part# 10038324, still a good # at GM. Price is $213.99 list, and $134.64 from some of the online GM parts sites. The Fiero Store lists this as their part #68324 at $149.95.
These (used) solenoids have been disassembled to restore normal vacuum valve operations, internal air filter replaced if needed, electrical vacuum sensor repaired or replaced, exterior cleaned to look like new, then vacuum tested and all electrical functions tested and verified for proper operation. Priced at $75.00 including shipping.
I would like to get one of these. I'm in Iraq with the Army, but my car is at the Fiero Factory after being a submarine in Nashville. I can send you a PayPal payment and you could just send it there?

Is there a guarantee for no check light? Do you still have them available? If I were to send you mine to have rebuilt, would the cost be less? I think the electronics are bad.... Is there an easy fix that I can do at home for the electronics?

While I cannot guarantee that you won't have a service light (there are other factors involved....see initial post info), rest assured that the one I send you has been tested and 99.9% sure to work. I can take yours in as a trade and give you $15.00, but you have to send it back at your expense. If the coil ("eectronics") is damaged, there is no real economical "fix" so these are not rebuilt and are disposed of. I have sold a number of these, and there has not been one dissatified response. (We do mark these rebuilts to avoid unauthorized "exchanges/returns" but that has not happened to date.) Yes, I still have these available.
I got one of these from Paul about a year ago and it cured my Code 32 problems. The code went away and has yet to come back so I'm satisfied. So, free plug for your product

Paul,
Add to this list that with combustion chamber temps higher gives a high reading for NOX on the emissions test.. been there, done that, 3-times to get my '86GT to pass emissions.
I'm shopping for the code 32 repair! Got engine light after warm up and at freeway speeds. Also seems sluggish. Must need a egr solenoid! Let me know? Thanks wyates@neo.rr.com
