Thanks Rab.
Don't know about black NTC sensor, 89 should have boost contoller*
Long story now. 89 N9TEA wagon has several mild performance mods. 80K on the 2001 re-build:
Arais custom forged pistons,
balanced con rods,
804 injectors,
2.5" free-flow cat back exhaust,
K & N cone air filter. (Apparently now considered to be a negative?),
tapered, (ala Jim Lill), throtle plate.
* in-line manual boost control @ 15 psi,
boost gauge & A/F meter on dash,
NGK B8H,(I think) colder plugs.
etc.
Car started right up & idled after 7 years in the barn. I got a used radiator from Brian Holm and popped that in. Swapped in the ECU from 88 sedan and took her out. Running pretty strong and hitting 15 psi before WG/controller dump.
Mobil 1 nice clean honey color, coolant in bottle pale green & clean-no bubbles. Exhaust clean & dry. External fuel pump whining a bit, maybe water in the filter?
So today, I began the wire & ground R&R / cleaning. I rigged up a starter relay, now starts first click. Cleaned & spliced new connectors on various top front sensors that were old, cracked & dirty.
My reward for this work was a very rich & rough start-up, accompanied by a sort of nasty loud grinding sound from engine bay. I have never heard this before. It's not real deep but I can't locate the source. Seems to come from the valve cover area but when I take off the filler cap it sounds good in there. Rich condition went away as I guess the computer re-booted the sensors.That
noise is a problem, though. Any thoughts?
thanks Chris
