Hi, The first place I'd start is have someone plug in an OBD reader and find out what code are stored and then you have at least somewhere to start. If you're not sure whatI mean, the plug is down by where your right kne is and it's near the console. It's a white plug that faces the passenger compartment. A device is plugged into that and reads the codes that have been stored. A mechanic can then give you a place o start looking from the codes that are read. He can also go for a drive while the device is plugged in and see if anything changes. If you already knew this, well, then maybe this'll help someone else. Another thought is the distributor being moved a little or the timing belt has a broken or breaking, not missing tooth> In any case, the firstplace to go is having the codes read. I hope this helps and good luck. I'm a '97 Tracker 2dr auto, 4wd, softtop owner and I've gone through a lot with mine. Steve H. May I add that you may have a burnt valve or blown head gasket, cracked head. A compression test will help eliminate these possibilities. Clay I finally broke down and took the car in to the shop, he suspected a fuel injector problem but found the problem, hopefully when he pulled the hose off of the fuel pressure regulator on the end of the fuel rail and gas poured out, it's supposed be be a vacuum so he thinks the fuel was pouring into the closest, first cylinder and flooding it til it burned off, we will know today as he ordered the part, $250, ouch
