    Misfiring 454, 1990 non-HEI

    High Energy Ignition, introduced in 1972 by Delco when Delco was a part of GM, only the V-8 had the coil in the cap, were external for the four and six cylinder engines. Was described as the easier cars to steal, just plug in 12V to that 12V terminal in the cap. Delco had to supply the...

    Misfiring 454, 1990 non-HEI

    See your 1990 has an EGR valve, vacuum thermostat opens it at around 160*F and this is when your engine is going crazy. Typical for GM a dual diaphragm, top port can check okay, no way to check the bottom one,, but apparently leaking causing your misfire. My 82 454 does not have one...

    Non working horn

    Ha, that was all that was, the horn, now programming for different options, cruise, phone, and radio controls, and in this case, the airbag. Also have multiplexing, youngest daughter purchased a base model Kia Soul, no cruise. All I needed to do was to purchase a switch for 15 bucks, original...

    Non working horn

    Ha, buy silver, supplies are running short and prices will skyrocket. Oxidizes is soft and arcs burn into it very easily, typically either brass or copper is used for the point material. Contact material they should use is tungsten, super hard, very arc resistant, does have a slightly higher...

    Non working horn

    Call these a point contact relay, only takes one speck of arc to prevent contact, back in the 50's we were using relays for logic circuits, point contact was considered the most unreliable. Much better choice was a sliding contact relay, self cleaning contacts, most reliable was a mercury...

    Shutting off during Hot weather

    Brings back some memories, bean counter special, 720 degrees in an ignition cycle, by firing two plugs at the same time 360 degrees out of phase, only required the crank angle sensor, cam angle was not required, this made the stock holders happy. For electronics, an ASIC was used, application...

    Non working horn

    Consider auto horns a throwaway item, typical are two, Low Tone 370 Hz. High Tone 420 Hz, around ten bucks each. Well except the ones on my motorhome and boat, chrome plated and external mount. Those had screws on it so I could take them apart, clean the contacts and good to go again. Most...

    2004 rear wiper wont shut off

    4WD's are sure popular up here with ice and snow, but any vehicle is worthless on ice, has several ice rains last season. All vehicles have 4 wheel brakes, often would see an SUV or pickup slid through a red light or a stop sign. Pickups are worse because they are running empty, no weight on...

    2004 rear wiper wont shut off

    Also a couple of U-joins in the drive shaft, another limited lubricated bearing, put well over 220K miles on several vehicles when they had zerk fittings.

    2004 rear wiper wont shut off

    I just block the vehicle up on my Douglas Fir blocks, don't trust those jack stands, with an assistant running the vehicle, get under there and look, when you see a CV joint jumping up and down, that is the problem. Hub bearings are done by feel, hand rotating the wheel, also side play.

    2004 rear wiper wont shut off

    Use to be a solid rear axle back there, practically indestructible, but half axles provide independent rear suspension for a much smoother ride. Not only the hub bearings, but that half axle can also be your problem. 99% of cores just have to be cleaned and relubricated with new boots. A...

    2004 rear wiper wont shut off

    Seems like shops like to take advantage of women, should know, have four daughters, last one was told her front hub bearings were bad and she will be killed driving this way, she called me, I can't believe this, bring it home. Only problem was stones stuck between the rotor shield and the...

    Grateful Memories

    Ha, six years in the military celebrated Memorial day by having a long parade in class A uniforms on a very hot day. Sure received a very fat Buyer's Guide loaded with Memorial Day sales, guess this how we are suppose to celebrate it. Ha, if I show my vet card, no discount on sale items, only...

    2004 rear wiper wont shut off

    Both my daughter's new Soul had steaks in both her windshield and rear window after a year with on street parking in Milwaukee, swore she was buying windshield fluid by the 55 gallon drum, after one year her wipers were shot. Rarely use them, believer in Rain-X. Did buy her a bottle of Windex...

    2004 rear wiper wont shut off

    Do you even use it? The rear windows are nearly vertical, strong vacuum back there that sucks up road salt and dust, if you do turn them on really leaves scratch marks on that rear window, kind of a self destructive device. Most likely the parking switch is not making good contact, question...

    Uneven Pad Wear Rear Discs

    Combined caliper service/parking brakes work just like a ratchet wrench, if you don't back it far enough to get that click into the next tooth moving it forward nothing happens. If applying the parking brake to compress the pads, if there is insufficient clearance, won't ratchet to the next...

    Uneven Pad Wear Rear Discs

    Sure love my 88 Supra, conventional calipers inherently self adjustable just like the front, but have integrated shoe brakes for parking, really hold tight. One key problem with calipers are the seals, as the pad wears, stick out further, and with this darn road salt, pistons get corroded...

    Daughter's cruise control is fixed, and she is really happy !!!! (so is Dad)

    Can go way back to my then father-in-law 86 Chrysler New Yorker, one year warranty, electronic dash went out, dealer replaced it. After 12K miles warranty was gone, drove a lot, about six months, dash went out again, dealer wanted 600 bucks. He drove up 300 miles with a black screen to let me...

    Daughter's cruise control is fixed, and she is really happy !!!! (so is Dad)

    Another common problem is lack of a good power on reset, program counters in a microcontroller have to be set to zero so they start reading code from the beginning. Most vehicles are still using the original 7805 voltage regulator developed my Motorola back in around 1970, a linear, that...
