I am having problems with my 1999 Chevy Tracker 4x4 Convertible also. The check engine light keeps going on and off, and every once in a while it will flash. When it flashes, it gets very putsy. It has never stalled or anything, but I also do not believe it is getting near the gas mileage it should be. I am thinking that it needs to have the plugs replaced and possibly the o2 sensor. The Code Scanner came back and said cylinder misfire?! Would that be caused from the plugs?
Any help would be greatly appreciated.

well, mine is the EGR Flow...I had it scanned. But yeah, if you havn't changed the plugs or O2 Sensor in a while, you probably should. Also, check the timing...that will cause like a misfire too.

I recently bought a 99 Tracker convertible with the 1.6 and I'm having similar problems. Check engine light on, with the code that indicates EGR system problems. Bad hesitation and no power. I replaced the EGR valve ($$$), exhaust and catalytical converter, but am still having problems. The Tracker has a pup converter (CA emissions?) which might also be plugged. That's going away shortly. New downstream O2 sensor also. If this doesn't fix the problems I'm not sure what else I'll check. The Tracker puffs smoke when it starts, so maybe new valve seals also. Good thing it was cheap to buy! Is it something with the 99s? This is my third Tracker, and the other two (a 92 and 94) were great.

Did you ever find out what was causing your problem. I have a 2001 tracker with the same problem.
Thanks in advanced

Thank you for responding to my message. Last week the mechanic at the Chevy dealer explained to me that the reason that the "service engine soon" light is still on after replacing the O2 sensor is that the four cylinders are running at low pressure (120 - 140 psi), and that one of the four cylinders is really bad (<110 psi). He said that the piston rings are shot and that the best thing to do is to replace the engine. He said that the present engine could continue running for 6 to 8 months. I hope he was telling me the truth because this is the third mechanic that I have gone to for help. I have been pricing 1996 Tracker engines and they run anywhere from $1100 - 3000. If anyone knows a mechanic who is really knowledgeable in Trackers and interested in fixing Trackers in Ohio please let me know. Thank you!

Is your tracker blowing any smoke? The reason I ask is that my tracker was also compression tested, and the shop came back with 140 psi each cylinder. They said it was supposed to be about 190 psi per cylinder. They then found out that my cats were nearly completely plugged. When they "cleaned" out my second cat (mine has CA emissions) it ran better. I'm hoping that when I remove the first (pup) cat, it will run better. I'm replacing both O2 sensors first also. How many miles does your Tracker have on it? Mine has about 160,000 miles, and the previous owner towed with it.

If you haven't already done it, it's an easy swap to replace the EGR valve. It's expensive though. Cost me about $300 for my 99. It will probably be less for the older years. If you do it, don't forget to clean the carbon out of the exhaust passages into the EGR (and the EGR tube if you have one) or the error will come back. I also think that excess backpressure (through a plugged cat) partially caused my error.

My Tracker is not blowing any smoke, at least not yet anyway. It currently has about 116,000 miles. The second shop that I went to changed the O2 sensor. The light went off for one day, but as soon as I got back up to 60 mph on the highway, it went back on and stayed on. Thanks for the advice about cleaning the cats. I will investigate that as well.

...so then the EGR Valve is located like somewhere on the exhaust manifold? Actually, I think I'll just have a shop do it. Was that $300 just for the part...or parts AND labor? Well, it doesn't really matter to me...I'll pay whatever I have to in order to make sure it's fixed cuz it has to pass emissions test too. In fact, you think I should go ahead & get a new converter too? lol like I said, the cost isn't really an obstacle...I just want it right.
