Re: 88 chev astro 4.3 computer codes.
14 = coolant temperature sensor / high temp
22 = throttle position sensor/ voltage low 32 =BARO circuit low (barometric pressure sensor circuit low) 33= MAP sensor These are the OBD 1 codes from my Haynes Manual.

Re: 88 chev astro 4.3 computer codes.
32=BARO circuit? Hmmm never seen that one before. I thought 32 was always EGR on GM OBDI vehicles.

Re: 88 chev astro 4.3 computer codes.
Yup, CD's right. 32 is the EGR. That's what I get for "sped redding". The 32 code "BARO circuit low" is for a carb'ed engine, doesn't necessarily apply to the Astro.

Re: 88 chev astro 4.3 computer codes.
Well it could. Some of the first years of the astro were carbed....
But an engine with FI should see 32 as an EGR code. I'd start with the first code and work my way down.... One may take care of another. But it sounds like you have a cascade of problems...

Re: 88 chev astro 4.3 computer codes.
For that many codes coming up at once, with sensors in such close proximity, I would start by checking the wire harness for loose connections or damage.
