1986 TPI Corvette intermittent code 33 - TunerPro RT

[rharker]

my intermittent code 33 ended up being a bad map connector. couple dollar ebay fix. might not be your problem. check connectors, maybe a short(which is hard to trace til it fails compldetely) make sure the maf ground is good and going to the other sensor's and ecm's ground. i heard they should be grounded in the same spot

Thanks - I'm quite sure that I have some bad wiring around the fuel pump relay and battery area which I believe is involved with the 2 MAF relays. It had some pi$$-poor splices put in there ... I already replaced one. I might need to buy another pigtail for the fuel pump relay to do it proper. Today it finally set the code again on the 4th day of driving but I didn't have my laptop with me. Friday I'll have some time to t-shoot.

Anyone have the BIN file for an AANK? It's not in the list here. I'm just curious what the difference between a Hypertech thermomaster and the stock prom.

Thanks,
Robert
