    95 MTX - No power, low mileage, computer reset restores power?

    Ah, I didn't know that. Thanks, I'll try to properly test it tonight.

    95 MTX - No power, low mileage, computer reset restores power?

    Fuel pressure was ~12 psi with key on, ~25 idle. Those numbers are probably quite low though, because the gauge I used couldn't completely press down the valve.

    95 MTX - No power, low mileage, computer reset restores power?

    Sometimes it actually doesn't help a thing, but when it does, it only takes a few minutes of driving to go back to normal (poor) performance. Would you recommend changing the O2s next? Thanks for the help:wave:

    95 MTX - No power, low mileage, computer reset restores power?

    Well I replaced the MAF, no difference. It has been running better lately for some reason - it no longer feels like it's running on 3 cylinders, and doesn't smell like gas so much. But it's still got no power. It can't be something like timing or clogged cats though, right? Because a computer...

    Where is this ground wire? I looked behind the glovebox and in the engine bay but I can't figure out which wire to unplug.

    95 MTX - No power, low mileage, computer reset restores power?

    Yes, the cold/hot issue is also present in my car. I'm pretty sure a shop changed the coil pack a few years back too. Is there a way to test the DIS?

    95 MTX - No power, low mileage, computer reset restores power?

    I have an odd problem with my 95 MTX. It bogs very badly and has no power, doesn't run smoothly, sometimes runs rich, gets 160 miles to a tank, and when I turn on the climate control (any setting) the rpms periodically dip to about 500, occasionally stalling. I've cleaned the MAF and pulled...

    Should I send my car to the shop?

    It has 122k miles, I'm reasonably sure that the 60k was done at the dealership. I just replaced the plugs and the wells were clean. I keep wondering what the mechanic did that made it run beautifully for 20 miles or so. Would this be possible with a stretched belt? How hard is it to pull the...

    Should I send my car to the shop?

    I had it in the shop a while ago because of poor performance. They repaced the crank position sensor and claim to have reset the timing, which was "60 retarded." Before I was home from the shop, the performance was bad again. It's been getting steadily worse over the last few months since then...

    '95 MTX has lack of power

    That's what I thought. Is it not possible for the belt to jump or something? I should just check the timing myself.

    '95 MTX has lack of power

    I had the exhaust opened up right after the cats - there's a joint only a few inches behind one of them. Like I said, it's very likely that they're stuck farther back but I don't think that's what's causing my performance issues. Seems to me, given the car's history, that the problem would be...

    '95 MTX has lack of power

    Okay, I just drove it with the mufflers bypassed. It was loud as a mofo, but the performance was the same. And as for the butterflies, I know they're closed when they're supposed to be because I can still feel them open at 4k.

    '95 MTX has lack of power

    Update: It appears that my cats are in my mufflers. I pulled apart the exhaust pipe just after the cats and stuck a coathanger up into the cat closest to me. It goes right through. Also, my mufflers seem to be full of something very heavy and rattle-y. Could this be causing my performance...

    '95 MTX has lack of power

    The pass code did come up. What would that tell me, if the butterflies close when the engine starts? And how can I tell if my cats are clogged?

    '95 MTX has lack of power

    I like to call my car the SLO... Super Low Output. When we bought it from the previous owner, it was fine. Performance slowly decreased until we brought it to a mechanic. He replaced the camshaft position sensor and reset the cam timing, which was "@ 60 retarded," according to the receipt. Well...
