    canadian 60k tune-up price?

    I'm another Vancouverite. Recently I had my heads rebuilt in Squamish after a timing belt failure on the Sea to Sky highway-- that's an incident that I don't want to have to repeat, and got my 60k taken care of at the same time. In Vancouver, a couple years ago I had some maintenance done at...

    Running on 4 cyls, strange tack readings...

    In case anybody's still reading this topic, yesterday afternoon I gave up and decided to take the car to a mechanic. I went to a place that I've been to a couple times previously-- they're inexpensive, the guy who runs the place is nice (though he's got a thick Chinese accent), and yesterday...

    Running on 4 cyls, strange tack readings...

    Well, good news and bad news today... Last night my new (used) DIS module arrived in my mailbox. It was cheap, too-- $21. Today I drove out to my box to pick it up. Installed it in the shipping company's parking lot. Fired up the car, ahhhhh, the smooth hum of the Yamahammer running on all...

    Running on 4 cyls, strange tack readings...

    Thanks for the help-- I checked the DIS last night, it's mounted with heatsink paste and connecting a good ground to the crossover tube provided no improvement. Also, it's not particularly warm up here in Vancouver, BC, especially not in fall/winter/spring. I'm nearly certain that my motor...

    Running on 4 cyls, strange tack readings...

    Hmmm. Starting about 2 months ago my 89 SHO developed an intermittent low-power problem, whereby it'd be chugging on only 4 cylinders. Pulled the codes, they indicated one of the coils was bad. I checked the wires running into the coil pack, and all of them had a power signal, so I replaced...

    Low power - Coil pack or DIS module or both? (pulled codes)

    In my case my problem's intermittent, and since my post the other day my SHO's been working perfectly-- I've got to wait for it to fail again to diagnose my problem further. In my case, since I was previously able to confirm that a signal was making it as far as the electrical connector to my...

    Low power - Coil pack or DIS module or both? (pulled codes)

    Noooooooooooooooooo! After 150km of driving, I just dropped a friend off, and as I pulled up by his place, I noticed that my idle speed was low, then it chug-chug-chugged as I drove off! argh! Crap, I'll have to bring my multimeter to school tomorrow and check around under the hood between...

    Still doing it

    My car hasn't ever felt particularly powerful from 1000 to 2500 rpm-- above there it kind of rockets off. It's always been that way. Anyhow, with your problem, how does the cylinder balance test check out? That would let you know if you're having any problems with any cylinders in particular...

    Low power - Coil pack or DIS module or both? (pulled codes)

    Mmmkay, so anyway, after chug-chugging my way to my auto parts people across town, I buy the new coil pack, hop in my car, fire it up, and as I drive off I realize that it's come back to life and I've got full power. Just swapped the new coil pack in; perhaps the coil pack was giving low...

    Low power - Coil pack or DIS module or both? (pulled codes)

    Looks like it's my coil pack; the DIS is sending signals out to all 3 coils, but I get no volts on the terminals for cyls 3&4. Edit: earlier when I did my KOER test (I messed up twice, third time it worked), I ran the cylinder balance each time, and each time it came out with cyls 3&4 being...

    Low power - Coil pack or DIS module or both? (pulled codes)

    The car: 1989 SHO with heads rebuilt 8000km ago. For the past couple of months, at idle there's been an occasional misfire-- nothing significant enough to make me want to pull the codes. Today I'd driven to school, parked for a couple hours, then I headed home. I left the parking lot, and my...

    Running poorly

    Have you tried cleaning the IAB? I just spent a while today cleaning my MAF and IAB-- my 89 started surging at idle last week, and has (for the past 20K) had a slight surge when stomping the throttle below 2000RPM. For a while I thought one of my cylinders was a little out of spec, though I...

    Rattling/squeaking in the engine bay - Need help diagosing.

    When the weather was colder out this winter, I was noticing some chirping and squawking sounds coming from a short distance in front of me, sounding like it might be in the engine compartment. The noise has gone away over the last couple of weeks (the weather's gotten substantially warmer and...
