Code 32 - C4 '90 L98 MAP - Suggestions / Solutions?
Wish the search function worked a little better so that I could research old posts - I'm sure this has been posted hundreds of times. That being said:
Recently replaced a bad injector (yes - only the bad one - not all 8) and reassembled everything back together. No noticeable problems - car starts fine and appears to be running fine. Only short trips around home up until today. This afternoon - took a 3 hour drive and the SES light popped on after 50 miles (1 hr) and remained on the balance of the trip. When I got home, flashed the system and received a code 32.
What a time for problems. This was to be my shakedown cruise - was going to get the smog test on Monday and then put the car away for the winter. Now I have to see if there is a reasonable solution to solve the problem prior to Dec 1st when the plates expire (and the snow comes).
Anything thoughts regarding something that might have come loose during the drive that was related to the injector change? Other items to check before I put it away for the winter.
FWIW - the car is relatively "low" mileage - with 21K. I think things are starting to go bad from age, not mileage... Have to drive it more next year!
Thanks for the suggestions...

Also,
Check the EGR Switch (if equipped) to see if the connector is coming loose.Its usually located in the crossover pipe in back of the engine.The white part on the sensor gets brittle and sensor wire backs out and gets loose.Happened on my 86,threw a code 32 but didnt run worse or anything.

Checking the shop manual - I don't show a "EGR Switch" - only a EGR Solenoid. The manual shows it location at the front of the drivers side of the engine - near the first injector. If it is where I think it is - it's a small, flat black package with two vacumn lines running into it.
While looking in the area, I did notice a vacumn line that was disconnected. It fits into a "L" shaped connector on the botton of the throttle body. I don't recall disconnecting it - and don't recall connecting it when I changed the injector. Hopefully - that is my problem. [Wonder why it took 50 miles of continuous driving for the fault to register...]
Test drive scheduled for tomorrow.

After reconnecting the loose vacumn line, the car restarted w/o the SES lamp illuminating. Took a 20 mile drive w/o any problems. I did notice that when I initially started the car after the line reconnection - I heard a rather loud, continuous "WOOSH" coming from under the dash - as if the car was throwing a vacumn discombulation fit. When I stepped on the brake pedal for the first time, the noise stopped - not to return.

EGR switch or sensor is located on the EGR valve. If it goes bad you can get a code 32. The solenoid takes the electrical input from the ECM and opens the valve so the vacuum pressure can open the EGR valve. No signal or no vacuum = no EGR. It takes awhile for the code to set for a couple of reasons. The car has to be warmed up since it is trying to sense the hot exhaust gas going through the valve. Also the EGR only works at mid range / partial throttle, so light or heavy acceleration don't open the EGR. You can also get the same code if the EGR sticks open.

The EGR valve runs about $40 bones. At least that's the approximate price for an LT1.
