<div>'95 Integra GRS, B18C1/JDM-B16, JRSC, VAFC
Ran geat until the gear/pulley on the water pump popped off and the timing jumped, leaving the intake cam 28 degrees retarded. *poof* Anyway, the car sat for 6 months til I had the time and money, took the head to the best machine shop in the area, put it all back together, everything checks out, compression, no CEL's, had to replace 2 coolant temp sensors that I forgot to take out of the head and the machine shop lost but otherwise all the electronics are the same as when it ran great. When I fire it up, it idles semi normal, fluctuates a little but not wild like when a FITV gets unscrewed internally...I'll worry about the idle later (unless it's related somehow). Throttle response seems normal...until it warms up then the idle drops to about 450 RPM and flat out will not tach up at any throttle position. The VAFC is reporting TPS values within tolerance (and it does respond normally when cold).</div> http://www.superhonda.com/forum/imag...1;ns/quote.gif note: the 2-wire coolant temp sensor that feeds the ECU is new but from a civic si...been going to honda dealer for head parts and Acura dealer for anything else that's a dealer part...could it be that the 1.6 civic ECT sensor gives a diff range than the 1.8 Acura ECT sensor? I hate to buy parts in "bingo swap" mode, but at this point that's all I know to do. Need advice before dropping more $$. Thanks!! |
Figured it out.
Poorly bracketed/mounted alternator and JRSC idler pulley was making the SC spin erratically....very rich at idle. Too rich to respond once warmed up. We fabricated the missing bracket that disappeared at the machine shop (when I took the head in...oops, my bad) and hooked up a bottom bracket that apparently hadn't been on for quite a while, did a little tuning on the fuel curve w/ the VAFC and *poof* ...... drivable. Still not perfect, but good enough to take it to a more qualified tuner than I to get it "right" :) Thanks to all who read and tried to come up w/ any ideas to this ummm odd problem. Even though I got few responses here and elsewhere, posting all over the place got me thinking more out of the box than usual...and doing the work w/ fewer beers than usual :) |
