SOURCE: HOW DO YOU REMOVE THE RADIO FROM A 1995 GEO TRACKER????????

To remove the radio:
Remove the ashtray by raising the armrest cover and removing the two screws at the rear of the ashtray. Slide the ashtray back and then lift it out. Be careful of the two front tabs, as you don't want to break them.
Reach below the wood console, where the ashtray front tabs were inserted. Loosen and remove the two wing nuts.
With a small, long flat bladed screwdriver, pry out the leather shifter surround. The leather shifter surround has a center chrome retaining ring, the leather surround, and then finally a black plastic surround. The chrome retaining ring has 3-4 tabs which are locked in below the leather surround. It depends on the year of the Jaguar. Probably the 95 has three, but maybe four. They should be at the front and rear of the trim piece (2 front and 1 back, or 2 front and two back) but I've seen then on the sides. The point is, you have to be careful with the screwdriver and find the tabs. The screwdriver should be slid between the leather and the retainer. Pull upwards on the retainer gently, and as you loosen the tabs, it will come out.
Remove the leather surround. Once the chrome retainer has been removed, it should be easy to work it out of the console.
Loosen the black trim ring gently as it has tabs as well, but they are visible once the leather trim has been removed. Lift it upwards out of the wood trim and pull it to the side out of the way. You don't need to disconnect the wires, just lay the black trim to the side.
Lift the rear of the wood console trim and gently, gently slide it back and up. It will try to hang on the leather console, and can be difficult. Patience is important, as the walnut on the ski slope cracks easy (really easy).
Once the wood console trim (ski slope) is removed, you should have a row of screws up the side of the center control panel, where the radio and AC controls are. There are four to six on each side, depending on what Jaguar used at the time, as the 95 cars mechanically are somewhat of a blend of the XJ40 and the XJ300. Remove these screws, and note any spacers that were behind them. These spacers get lost quickly, and cause the ski slope to sit awkwardly on the console.
The radio will slide forwards once these screws are removed. Remove the radio harness and the antenna lead. As the books say, assembly is reverse of removal.
Good luck, and let me know if you have questions. If you are replacing the radio, let me know as I have the harness wiring codes and can help you with that as well.

SOURCE: what are the symptoms of a bad egr valve ina 1994 geo tracker?

this may help
EGR Theory. EGR serves one purpose and one purpose only. That purpose is to reduce Oxides of Nitrogen (NOx). Undernormal combustion, Nitrogen(N2)Oxygen (O2) in the air and Hydrocarbons (HC) in the fuel combind into water(H2O) Carbon dioxide (CO2) and the Nitrogen remains unchanged. Under very hot combustion temperatures, the Nitrogen reacts with the other two byproducts and forms Nitrogen oxide (NO). After being released into the atmosphere, it picks up another Oxygen and becomes Nitrogen dioxide (NO2). In the presence of sunlight,
it combines with other compounds like Hydrocarbons and forms Smog. Since exhaust gas is inert (very stable) it doesn’t burn again. So by being introduced into
the combustion chamber, it will lower combustion chamber temps enough so that
the Nitrogen doesn’t react with the other compounds and is passed unchanged out
the tailpipe thus not contributing to smog. Now, since exhaust gas doesn’t burn, it
doesn’t exactly help with combustion. At higher RPM’s, this really isn’t noticable,
but at idle, the reintroduction of exhaust gas will cause a very rough idle and can
cause stalling if to much is introduced into the combustion chamber

SOURCE: reset check engine light on 1995 geo tracker

I had the very same problem with my 94 tracker and it turned out to be something simple. My check engine light had popped on after it had hit 100,000. I went through all of the suggestions that people had suggested (unplug battery......etc) and still to no avail. Searching the internet, I came across a website called suzukiforum.com and there, this guy was able to help me with my problem. It turned out to be a maintenance switch that kicks on every 50,000 miles. This switch is like a secret that the auto manufactures use to ploy owners of their cars to bring to the dealer and then rack up the dollars in unnecessary "repairs". The switch is located under the dash and can be hidden anywhere. From the assistance of the guy on the forum, he was able to send me photos of this damn switch and possible locations where it may be mounted. I found mine in about 5 minutes, where it was attached to the steering column. It's a tiny switch, that you slide up or down, depending on what position it is in upon finding it. If it's up, then slide it in the down position and visa versa. Once you do this, the check engine light will go off. Make sure you do not have the car running and you can even unhook one of the battery posts, just to make sure you don't hit anything while rooting around under the dash. Good luck!

my guess is you meant changing carbon core
HV spark wires, but the plug wells are like oil pits. (flooded) SUPER COMMON.

(not spark tips carbon-ed up. right)

http://www.fixkick.com/IGN_timing/tune-ups.html#SETS

get he MAG wires and win.! max life and better spark!!!

all G16b do this seen 100s and all C.O.P engines.
1 cause
owners did not do full 60k mile tuneup
per operators guide, lost it have it ask.
the valve lash step, demands a new valve cover gasket set.
if not it will fAIL, it will,like pissn on a sparkplug
bam. like texas talk, i do...sorry

and a cam belt.. forgot that too?
that is fail 2 , in the woods,
or like train light in the tunnel.

not one of those parts last the life of engine
the real reasons tuneups were invented
and why planes dont crash (of ddumbb things like this)

tuneups on this engine, only make long walk home
on other engines, most DOHC. boom head valves bent or far far worse.

if lost

94 tracker 1.6 mpi wont start


I'd say your ECU module has gone bad. I highly recommend the guy I found on eBay that was rebuilding the modules exchange , he installs a performance chip in the modules and your Tracker will have 20% more power! You can probably buy the chip and install it yourself if you know a little about electronics, ground yourself when installing the chip!
