Question about 2002 Chevrolet Tracker

1 Answer

I have a 2002 Chevy Tracker with a 4 cyl 2 litre engine that has an intermittant miss. The miss generally shows up after it heats up to normal running temperature. I've replaced the plugs, air filter and gas filter. Got a message on a code reader that the engine had a missfire on cyl #3 so I switched the coil from #1 to 3 and visa versa thinking that I might have a bad coil on 3 and if the light came. After about a week and a half the check engine light came on again and so checked for message. Miss on #3 again, so I'm assuming that the individual coils are all right. Any ideas?

if you have changed the plugs and wires you need to do a cylinder balancetest and find out what cylinder is missing after you find out what cylinder is bad check compression if it is over 100 check your injector

SOURCE: 2000chevy blazer random cyl missfire number 1 cyl

Just to let you Know what you R getting into-I just got rid of My 2000 Blazer (THANK GOD)!!!! If you check out the Recalls and Complaints Online for the 2000 and Up Chevy Blazer you will be Reading for Months!!!! I am Chevy to the BONE and bought this for My Wife-It was GREAT for the first 15000 Miles and then Everything went Haywire! The Seats Broke, Lights quit, Tranny went Twice, Brakes Failed 3 Times, NEVER Ran Right again, Guages quit working, ON and ON and ON. GM will NOT honor these Recalls and Fixing them is REALLY Expensive. Just MY Opinion But, GET RID OF IT WHILE YOU CAN!!!! Took a BIG loss on Mine and Don't Regret it!!!!

Now change the distributor. Get one from salvage or e-bay. Did the timing belt jumped a tooth or is it new. Vitally

How to test oxygen sensor (s) 2002 chevy tracker?

The sulfur smell is because the 4 cyl is running rich . The issue can be the maf sensor or the 02 sensor going bad or the car needing a tune up. If the sensors are going bad there should be a check engine light on. Read the code for free at any parts store and then google the code they give you for more info on fixing the problem.

Some good news is the sulfur means the cat is functioning.

hope that puts you in the right direction

What kind of oxygen sensor is need for a 2002 Chevy Tracker

Since you said 4 sensors I will assume you have the V6 engine.
The aftermarket sensors that are designed to fit your truck are about $150 each so with labor that would be about right. And sensors from GM would probably be $250 each.
However, odds are you do not need all 4 sensors. Maybe one.

Chevy tracker 4 cyl 4wd 2003

Most major auto part chain stores have a loaner code scanner (they require you to leave your ID while you use the tool in their parking lot). There is a connector under the dash near on the drivers side that accepts the reader....check the codes and Google them for repair info or post them back here.
