Idle Rpm Too High.

NOT told TOO HIGH OR TOO LOW, and what the RPM now.????
800 RPM hot is par for hot idle.
in USA all are cars 1988 up EFI are controlled by ECU and not the humans did with carbs in the good old days/ by LAW here.

HOT idle RPM or cold IDLE RPM.??? or both are wrong.
not told that. and is key to any cure for sure.

Toyota glanza ep91 turbo , manual

what country is it. sold to first. (market export)
1989 to /96 car?
I bet this is the real name, fully]
Toyota Starlet 1.3 Glanza V Turbo (EP91, Japan)

glanza V was powered by the turbocharged 1331 cc 4E-FTE
ECU controls actual turbo and injection rates and more.
and sold to
Japanese market, although some used private imports made their way to the UK, New Zealand, and many other right-hand drive markets.
most cars but gee 1989/96 are very old cars.
had 2 idle speed controller. (this is pure experience not your car that the USA does not have)
IAC (thermal controlled idle (coolant temp.) only
ISC (ECU control hot idle above 65C coolant temp)
this how all ours worked here, 1986 to 2000, then the ISC took over all idle controls.)
no 2 engines use same controls,
on some old cars high idle hot is caused by these factors.
1: coolant never gets to 82c(bad thermostat)
2: vacuum leaks.
3:IAC bad or ISC , clogged up, and jamming/sticking
3: ECU is stuck in limphome, idle controls suspended.
4: on our cars the EPA dictates IDLE and has no screw to set.
5: TV plate gummed up and sticks (throttle valve)

the best answer is to first buy the service manual
and read ISC page (idle speed controls) ECU controlled.
read IAC Idle Air controller. page. water temp controlled.

Here are the 3 engines listed for this year. IGNITION TIMING

2002 Nissan/Datsun Truck Frontier Pickup 2WD 2.4L SFI 4cyl

The Ignition Timing

18-22 DegreesBefore top dead center - When throttle positionsensor disconnected and using suitably programmedscan tool.When adjusting idle speed, set parking brake & chock drive wheels, curb idle speed (750-850 RPM)transmission in neutral.

IGNITION TIMING

2002 Nissan/Datsun Truck Frontier Pickup 2WD 3.3L SFI 6cyl

The Ignition Timing

8-12 DegreesBefore top dead center - throttle position sensorharness disconnected.When adjusting idle speed, set parking brake & chock drive wheels, curb idle speed (700-800 RPM)transmission in neutral.

I've seen from 500 to 1500 RPM in all the manuals I've been through, depending on the year and application (truck/car). In personal experience, 650-800 RPM is acceptable warm operation range. This will also depend on elevation. Will go up to 1200-1500 RPM for cold starting. I live at about 2000ft and my '86 Pickup 22RE idles at 725-750 like a top after about a 3-4 min warm up @ 1250 RPM if it's cold (<45ish).

Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

adjust your idle screw to a higher rpm to stay runing

You have extra air leaking into the intake manifold that mimicks a throttle that is open further than it really is. Check for vacuum leaks.

check for a air leak in you sistem, or check for aditional idle screw adjust in the another end af the accelerator propel

your throttle position sensor might me bad or out of adjustment. if it is out of adjustment then it can misfire all the way up to 3500 rpm.
i had a friend that had a miss fire at 2500 rpm. i adjusted the tpss right and the misfire went away. Check for engine codes by jumping TE1 and E1.
Your fuel filter may be dirty and restricting fuel to your injectors.
have your fuel pressure checked.
