I have a 1991 Chevy K1500 Silverado with a 350 cid. I just put a new crate motor in this truck about 6 months ago. Since then I had a code 43 and troubleshot it to a bad knock sensor controller. Lately at highway speeds I've seen a huge loss in gas miliage and performance, also at these speeds (65-75mph) the temperature gets up to around 220-230 degrees and now it is poping a 32 code. I was thinking maybe the catalytic convertor, but I don't want to start shotgun troubleshooting and ending up waisting money...please help with any info you might have. Thanks.
