probably got a bad IAC motor
Can a 2001 Suzuki Vitara 2.0 Engine be swapped with a 2001 Chevy Tracker engine?
In order to tell you that you would have to describe the noise and what the car is doing when the noise is made. Are you idling, driving, just turned the AC on? What is occurring and what is the noise? Idling and sounds worse when AC is on. Sounds like it is coming from the top of the engine. Vehicle has 120k miles
The 2.0 liter Suzuki engine in the Chevy Tracker uses 5-1/2 quarts of oil to function.
I had a check engin light on for years on my 99 tracker the mechanics couldn't find the problem, I bought a new gas cap (3 dollars ) it turned off and hasn't turned on since, its been four years.
with a rev counter
in the back, behind the engine
with regular oil changes I've got 250,000 + on my 98 tracker
Pull the engine.
It's lean. Could be something plugged in the carb.
BEHIND THE MANIFOLD..ON THE LEFT SIDE OF ENGINE
most likely a 2.9l or a 3.0l Depends on your model
if you smell it inside, it's the heater core it has a leak.
