but only at startup.
lemme mention, this is my mother's car.
about a month ago, she complained that if it was wet outside, car would sputter at first start (with about 200 rpm drop)_. she also said that she would lose power assist on steering if it was wet out. there happens to be a big ass puddle near her house, so i figured it was, at worst, dead plug wires taking a drink, and water getting under the belt. (spark is from central coilpack, no rotor but wires are still there on this year).
drove it, and found that it would do it at any startup, not just the first of the day. decided to replace her 120k mile plugs (only good for 100k miles). they were worn down as hell, replaced them with conventional copper 30k mile plugs instead of the 100k platinum (only ones i could get right then). long story short, the problem went away for about 3 weeks....then
the problem comes right back, this time it happens at EVERY startup, and goes away with running (either it goes away or decreases in volume till you can't hear it anymore). the problem is categorized by a popping sound heard in the catalytic region, very low idle speed when D is engaged, and very high idle speed when park is engaged (1200 vs normal of about 800). as (cough cough) many women don't like to spend money on parts they might not need, i was able to swipe plug wires from the vulcan equipped 98 ranger that also lives in her driveway. same thing. im going to try to swap the coilpack today as it has the same PN# on it, and see if its any different. bill r showed me ford's tsb for pinging and the MAF wire. i will clean it again. i will also clean the Idle motor. any thoughts as to what it could be? im trying to logically narrow down the parts that would be working CHIEFLY at startup....i just hope it isn't a computer.
