dirty rotten C.O.P.s

datz right imma C.O.P. hater. i bought a certified used toyota back in ’12. during the 100% warranty period the car died and i got it towed to dealer. they wudnt tell me what went wrong. even the paperwork wuz vague. something about a sensor. sometimes i wud step on gaz and nuttin wud happen. finally crapped out.

it ran after service but it always hesitated just a little. i changed the plugs at 70k miles and i often changed the “r” filter.

just few days ago after i had the front end aligned and new tires on the front the check engine light illuminated on dee way ter work. it stumbled twice but i got deer and back ok. lucklishly i haz OBDII reader and it gave code p0351 primary secondary coil malfunction.

an inter tube search indicated the #1 COP which is coil over plug. back in dee olden dayz carz had won ignition coil that wuz “distributed” to each spark plug by a cap and rotor mechanically inter locke dto timing gear. it’s all dun “E” lectronically nowadayz. each spark plug has a coil sitting on to of it.

in the olden dayz you had to replace the rotor and cap becuz the spark wud corrode the contacts. the coil never went bad.

well, this coil went bad, one of four. after market replacement wuz 75 uhmerikan bux. old tyme coils were 35 bux. but at least once a yeer you had to replace the mechanical parts, mebbe 25 bux. so actually replacing this COP is way cheaper over the ownership period.

will duh udder wonz fail? mebbe, mebbe knot. the replaced COP had orange dust on it. i pulled duh udder tree and dey had orange dust. i wiped it off wiff a clean rag. duh orange dust is duh insulating boot breaking down from high voltage leakage. warnt burnt true but i seen some carbon on dee plastic nose duh rubber boot iz attached to. i know now dat when car stumbles it will mean failing coil.

the #1 plug didnt “snap” when i unscrewed it. prapz bean a bit loose let some combustion gases leak by. udder wize it looked ok. i replaced it and tightened it up some more. i tightened up duh udder plugz wiff out removing dem. although i bought replacement plugs i figgered i’ll do it on a nicer day.

the auto parts clerk gave bosch plugs dat didnt fit and i buttoned duh car up and returned dem. i hex changed for auto lite which are correct size and i get a gift card rebate.

ebber since i had dee car it intermittantly stumbled even after warranty repair but dee check engine lite never ever came on. for dee past 2 yeerz it haz ben annoying with the stumble but knot always. duh new coil haz seemed to eliminate diz problem. i’ll be driving it for duh wek and i’ll know for sure.

yesterday i pulled the code and erased it. i hosed off the MAF sensor with special cleaner and put in a new”r” filter den drove it. well, after 10 miles or so duh check engine lite came on again wiff dee same code.

it bean very rainy all i cud do iz park dee car and research. datz wen i red about dee orange dust.

diz car has over 115k miles. when i replaced duh original plugs i had to lean into it to snap duh seal. in fact it was scary tite. i put some anti seize compound on new plugs and i thought i crushed duh compression ring but mebbe i didnt. i cud have contributed to duh coil failure. anti seize compound residue on duh plug well coming in contact wiff duh boot.

i had to have duh positive and negative bat tree cables replaced a few yeerz ago. i noticed today one of dee ground wires was pooty corroded so i replaced dat. diz engine haz ground wires all over it. boffins say dat poor grounding can cause all sorts of strange problems.

the body iz just starting to rust and it is high milage. the a/c compressor failed. i had the struts replaced all around so mebbe i’ll just drive it into dee ground and toss it. udder wise it haz ben extremely reliable and cheap to run.

1st world problems.
