2002 Chevy Tracker will not idle

you forgot to say hot or cold engine so is 2 answers.
they had 3 engines that year (the nn = liters)
G16, 16valve i4
j20 dohc i4
H27 v6
nobody on earth can guess the engine, and is an engine question
2000 is 100^% normal on any cold engine, 1500 to 2500 range cold
based on coolant temps -30f to 180f.
the colder it is at starter the faster the idle, and is AIC controlled
when hot the engine ecu goes to full hot (normal ) engine rpm controls using the ISC.
the exact parts are not the same on the 3 engine ever.
next time tell engine and if RPM is cold engine or hot.

btw I owned all 3 cars before, so have full documentation on them.
and restored them too. and can field most questions.

I think I would start by changing the broken TPS with a new one.

If there is cold air coming out the heater than there is air in the system. After you replaced the thermostat did you run the engine at idle with the radiator cap off until the engine came up to operating temp? Doing this will purge the air from the system.

Could be your alternator or a bad idler pulley. Is the transmission good? It may be the tranny or your differential whining.

This is caused by one of the things you already replaced , including the A/C compressor and power steering pump. Or it could be from a wrong size or over stretched belt.

Hi, here is the location of the fuel pump replay below....



Hope it helps....

a/c compressor froze up? Won/t turn?

if i remeber correctly your vehuicle has a transmission switch that has a power mode and normal mode. look for this will be on center console or dash. the power light just means it is in power mode

check the idle sensr, also buy an scan tool, check the code, a sensor or too are bad

the plungr may be bad try a new one
