Default 1988 Vin C Questions

Finished up my Delco Ignition Mods. and all came out well. (very easy to do). I have a concern about my lower radiator hose, it touches the harness exiting the module, I am thinking this is a cheaply molded replacement hose or when some nose bodywork was done they may not have placed the radiator in the correct location.

Any thoughts on this? How close is your lower hose to your module harness??

Trouble Code 64 and 65 on my car, OTC 2000 says all is well with the EGR (goes up to 86% on hills, 0% on no throttle etc. etc.) My question is where does the ECM get its feedback from to determine that the EGR is bad and set a code?

Still need info on wether or not my 1988 C engine has a Chamferd or a counterbored hole in which the timing chain tensioner bolts to?

Any thoughts on the above will be appreciated!
Thanks

Well the Delco module is somewhat longer which places the harness closer to the radiator but was not anything I was bothered about. Module is some inches above the radiator hose so am not sure what you mean.

I too am unsure how your wire harness could be near the hose. I just did this myself, and I barely had enough slack in the harness to accomodate the longer ignition assembly. Perhaps the hose is not correct, like you said. Or maybe the wire harness has been played with or rerouted? At any rate, it shouldn't really hurt anything as long as nothing is actually wearing away at the wire insulation or the hose. The temperature I don't think will be too hot, since that is the cool end of the ratiator, if I'm thinking right.

And, I've got no clue on the rest of that stuff.
