    Center Dash Head Unit

    They make single DIN head units with big touch screens that are somewhat adjustable in angle and vertical position. I've thought about one for my 90 because it was DIN from the factory. But the large price tag has kept me using my existing single DIN head unit bc it already has blue tooth...

    Spark plug wires

    last set I got was from Oreilly's according to my email. they fit ok, definitely not custom. i just replace the wires one at a time and use the closest length new one. My OEM wire holders are long gone, so I just ziptie them up out of the way of things. ACDelco Spark Plug Wire Set | ACD 9618V...

    '88 TBI Build

    hooker makes some, but no O2 sensor bung. you'd have to add it to the exhaust just after the manifold.

    1982 Tailgate Stuck Down

    section 10A5 of the service manual (at least for my 1990) covers all things end gate. seems like it is possible to break it down with the window down. I'd check out the 1982 service manual and see what you can find out. in the Reference Library if this forum.

    Timing advancing too far

    TPS voltage is a tad high, but likely not causing you any issues. You can slightly bend the tab to lower the voltage to a little closer to 0.5v at idle, but not critical. IAC counts seem high for sitting at 195deg temp and warmed up. You may try a reset on it. Jumper A and B on the ALDL with a...

    Another "Dies at stoplights" Issue

    it's a game changer for diagnostics. TBI can still benefit from some old school mechanics (vac gauge, etc), but being able to see what the computer sees is huge to make sure all the sensors are working properly.

    Another "Dies at stoplights" Issue

    i recommend getting ALDLDroid and a Bluetooth ALDL cable to see what the computer sees. it's a minor investment for near-scan tool capabilities that will make diagnostics on TBI much easier. that and the drivability and emissions manual in the reference library of this forum. It is like the...

    Windshield Wiper Pulse Issue

    sounds like the park switch in the motor for OP. it's not intended to be serviceable, really. but if you are adventurous, it is possible. i'd replace the motor with a WAI motor if it isn't parking. if everything works properly except the delay, it is likely the pulse module. it too, is...

    (solved) Tbi injector not pulsing on startup

    might be PCM because of the 4L80e transmission and it also controls the transmission. P - powertrain? the ECM only controls the engine. so yours is a PCM. my 1990 suburban with 350tbi amd 4l60 is an ECM. E - engine?

    (solved) Tbi injector not pulsing on startup

    I believe they use ECM and PCM interchangeably. and yes behind the glove box is where it is located.

    (solved) Tbi injector not pulsing on startup

    find the drivability and emissions manual for your rig and follow chart A-4 for injector diagnosis. in the reference library of this website

    (solved) Tbi injector not pulsing on startup

    $40 well spent on OEM buzzer

    agreed. I like the buzzer for lights and key in the ignition.

    Need Some Help Here

    after you jumper A and B, turn the key to "on". then the light will flash codes. otherwise solid advice. I'd also check the no start chart in the service manual

    Rear Main Seal

    I did have a rear main seal leak once and Bars rear main seal repair did help slow it substantially before it was replaced. but I think OPs sudden increase in oil leaking is more likely a result of the recent intake manifold RnR. or at least that's the best guess until he tracks it down. I...

    Heater Core how to

    do all the settings work properly? what is shown looks like "bi-level" setting. make sure the vacuum lines haven't been swapped around on the main control unit.

    Cruise control works for a while then starts to lose speed

    highway cruising vacuum may be 10-12 inches at 75mph or so. I'd guess at 55mph it would be higher. check your lines and reservoir well. with the system off and holding vacuum, wiggle and jiggle the lines and see if it drops. if all is good there, you may have to take the solenoid apart and...

    Do I need different gears with 33” tires and 4” lift

    detroit/eaton makes the truetrac. it is a gear driven posi and doesn't require additives. very good street manners and very good offroad. just not a true locker, so if you are crawling over rocks and hitting difficult trails and putting tires in the air, you may want something different...
