You replace it you do not fix it.
The recommended compression for a Geo Tracker engine is typically around 170-190 psi for each cylinder. This will ensure proper engine performance and combustion. It's important to check compression as part of regular maintenance to catch any issues early.
You don't fix it, you replace it.
kick it. that should help
Locked meaning blown?,no quick fix.
replace the exhaust.gmjim
That depends on what it is doing or not doing.
You have to take it apart to determine what is wrong before you can fix anything.
The first two Geo codes are for the interest area for a career
Fix the part that is setting the code in the first place.
