    My stepdad and are drawing a blank. My 1995 1.9 lx runs beautifully for a minute or two then the timing flips about 180 degrees. We've alligned and realligned the timing marks over 15 times now. Maybe one of you can provide insite? PLEASE HELP!!!

    Sometimes parts stores hand folks the wrong type of timing belt. If your cam/crank sprockets are round-tooth, make sure you get a belt to match. Early year 2nd-Gen 'scorts were square-tooth. Manually turn the crank and note anything unusual. Same for the camshaft. It should be noisy but it's possible that a neglected hydraulic roller lifter can intermittently hang-up, briefly lock the cam and cause the timing to jump. The only other possibilities are not routing it properly, not securing the tensioner lock-bolt, and/or taking up ALL the slack on the long straight side of the belt between cam & crank.

    15 times? I think I would have stopped and questioned the results after about 2 or 3 times. Are you watching the results with the timing covers off?

    ...and eyeball the water pump pulley. Wobble, wobble means replace, now.

    That's my stepdaughter and mechanically everything is good and the belt is not slipping. When we shut it off the
    Timing marks are still able to line up. I can't find any vacuum leaks. I'm thinking maybe the crank sensor. But I don't think that would throw it off that bad. Could it? What else has the ability to alter sparktiming to such extent?

    Haven't chipped a tooth on the pulley so it's syncing on wrong gap or something?

    Hum, by the way, doesn't the coil pack fire 1 and 4 and 3 and 2 together. So you get wasted spark on the cylinder 180 off, so how exactly are you determining it's 180 off, and if it's exactly 180 off, it shouldn't actually run any different.

    When it flips it sounds like it is missin on 2 cylinders and it's low on power. Don't think the teeth are chipped but I'll check. This thing is really irritating me. I was really busy so I dropped it off for a thermostat job at a local shop and picked it up with a blown head gasket. I took the head in and had it resurfaced dropped it back on with a new gasket and bolt kit. and it was good for a few days now this. I usually do all my own stuff and this is why. A simple thermostat has turned into a nightmare.

    Again, how are you determining the timing 'flips'??? What shows you that?

    Coil pack bolted back to head nice and tight?

    Also, pipe the temperature senders are in is bolted to block? That's it's ground, CTS has a lot to do with timing.

    I am questioning this myself. I say this because the crank rotates 2 times for every 1 rotation of the cam pulley. This allows for every other crank rotation to appear 180 degrees off!

    ^ That's probably what it is.

    I'm coming in a little late on this question, but number one, are you still there? I haven't seen any other input from you on this question.

    But MY first question would be this: What are you finding [position wise] when you've done these multiple "re-aligned the timing marks over 15 times"? Seems to me you're saying that if you've "re-aligned" it, then it was "NOT aligned" when you inspect it? meaning that it jumped SOME teeth? but if that's the case, how can it just "happen" to jump 180 degrees every time?

    Maybe my understanding is way off base, and yes, I'm familiar with the "waste spark" concept.

    Oh you know what, I think this is a "runs beautifully until it goes into closed loop" whereupon of course, the EEC takes control of the timing and your timing light will see it wandering around from base..

    So set up the timing, leave it alone, go hunting for the sensor problem or vacuum leak (Or if you're unlucky mechanical problem) that's making it run crappy in closed loop.

    #1 suspect, dirty MAF.
    #2 suspect vacuum leak

    Sorry guys I'm still here just been real busy. Waste spark wouldn't do it cause there would still be a spark tdc. I don't have obd 1 so I think ill try to bulb the port and pull codes that way. Hopefully that way I will find the issue.
