spent the two days before Christmas at friend Terry & Liz's home in the Town of Newburgh, where my Kammback & GTO are stashed: my '89 Cherokee was on it's last legs - surging at idle - dumping raw fuel all over the exhaust manifold from #3 injector body - which negated using my newly resuscitated interior HEAT - seal leaking - mileage measured in tens of dollars........ we'd a Haynes manual for the Cherokee Terry'd picked up at Parts America - not one 'Spec' could be found on any page - O2 sensors shown with the Universal single wire - no sizing of anything - forget finding a plug gap. gonna' relocate that manual right next to the dumper in the washroom where it can apply said collective expertise -;) :- ...... ....... ........ the O2 sensor is 'Original' ......with 174K miles on it - outdoors & up on a floor jack, we ran the engine after disconnecting the sensor pigtail - not much difference - the ECm hunted but overall that O2 sensor was shot - and frozen... Terry builds custom Homes & holds a Masters in Geology - his idea of a relaxing weekend is in mountain caves, hauling bags of equipment on a rope - took him 15 min. to m'oose' out the O2 sensor - and the threads ..........were gone right down to the barrel.> Nightfall . Christmas Eve day we hit car friends - Sears and every auto parts store in the region numerous times collecting parts & looking for a Tap & Die set for that then unknown size O2 sensor. after thawing my brain over a java - I commandeered Liz's Dell & ran a search on STROKERS at yahoogroups: came up in one odd post on using a generic Chevy O2 sensor and making bungs to fit: "the 18mm FORD spark plug size O2 sensor..." > [GM is crucial with AMC in some peoples' minds...] I'd seen an 18mm thread chaser in a Parts store we'd been at the day before > now on our 6th run for the morning - > Terry reconned the FORD F-150 to the > coffee & 'organic' cigarettes store for bolstering supplies. the Parts store counter girl was pretty sharp, chewed chaw tobacco from a tin - her younger manager fresh out of high school knew his store and JEEPs cold, he ....gets a Gold Star. getting at that O2 sensor orifice is NOT a fun job - on a rocky dirt drive - floor jacked & a slab of plywood that didn't stay in place - wind chill was single digit - and blowing the sun out of the sky - Hudson River Valley style. getting a thread chaser started where there are no threads - there are no words......but Terry chose: "...this Whore..."... chaser went in - about 3 threads worth - AMC for '89 placed that bung on the exhaust manifold - not the header pipe - point being : it would cost more than my Cherokee is worth for a shop to pull the manifolds for a heli-coil....... easier to find a Cheep Cherokee & swap out the tires than split the manifold with the hardened chaser. should that O2 sensor blow out - I figured it'll hit whoever is passing me just above their pelvis - as my engine compartment ignites..... Mark Price sent me a set of injectors he'd swapped out for a freebie new set - these came with roughly 84K miles on them - some 90K miles less than what I was running - THANK YOU MARK ! how cold was it ? the new injector seals were splitting when installing - had to salvage some of the 2 month old seals off the outgoing injector rack - and apply dishwashing liquid to grease them into the injector rail cups & manifold seats . fired her up - > ran much better - still rich at an unusual idle - and #1 injector body had some w'eepage' just below the plastic ceramic top - not a lot - but noticeable . another coffee run & the weepage seems to have ceased for the time being - she's A1-A. the distributor cap & rotor & wires were next - yeah baby ...... Terry spun the head off the cap bolt - leaving a rusty shaft. the rotor had rust on it - the cap contacts had hard white oxidation stuff covering them, with a single black dot in the centres...... machinists wire'd the one side of the cap down - thank you Rube Goldberg. another coffee run - and a $20 for the tank: Cherokee making nice power in a much crisper fashion - idle still sucks: above 1K rpm - the engine is fine. below at idle, it drops to near stall - surges - stabilizes then falls again....... and runs rich. we hunted all vacuum lines - they seem fine, no splits or rot - ..... every so often, I get a 'hard pedal' for the brakes which might be the master cylinder vacuum taking a hike - but overall - a two day X-mass Eve I'talien Army field service' - time well spent........ my thanks go out to Terry - Mark Price and his meretriciously packaged 6 injectors - a Tobacco chewing counter girl - her way sharp store Manager - Erve Hamilton for searching his barn in freezing evening weather for a Tap & Die set - American Spirit Organic Lights smokey treats - and the Mobil Convienient Store coffee supplier - Liz for her great Lasagna dinner amongst Christmas Trimmings that brought back early memories and a smile. For laughs, I thank 'Paulie' - Terry's African Grey bird, who correctly imitates doors squeeking, handles turning, phones ringing, answering machines, and Terry's smokers cough & early morning nasal congestion > I nearly fell off the couch laughing........ for sneers, ...... the mouse currently inhabiting my Kammback. NEXT week, that sucker better be on a flight to West Palm before I hit town ;) =Bt= milnersXcoupe "The Heretic" _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
