WHAT YEAR? CAR.
the engine tachometer reads what.
that whole post is a contradiction.
ahh, you mean the engine does not accelerate, or the engine bogs.
600 RPM is why below, 800 normal (most cars)
the engine stalls, well sure it will as low idle speed will surely do.
so the real post is my engine stalls.
and if i try WOT ,it will go above 600 rpm in or out of gear?
wot means wide open throttle.
can the engine race to 3000RPM in PARK (or neutral)
if engine power is ok, full WOT power up a hill and is only and idle problem say some. and we work bad idle.

the top reason for stalls (besides #1 never ever doing the 60k mile service,repeats at every 60k)_
is a stuck open EGR (part of same service to do that but Ill add that)
or stuck closed ISC (electric IAC)

SOURCE: Oil Pressure Light Comes On after 10 min of Driving

You may not have put the right amount of oil in your car, your oil pressure sensor could be faulty, or you may have a leak.

By revving your engine, you're increasing the pressure and thus turning off the light and making the sensor think that it's at the correct pressure.

SOURCE: nissan ga15 engine idle adjustment locations

The idle speed is computer controled, it is not adjustable, you most likely have sludge in the throttle valve and the idle speed control air bypass valve, clean them with carb spray with the engine running.

SOURCE: engine high rev at stop and slowly goes to idle speed.

I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck

SOURCE: Car stalls when put in 'drive'

Check your air horn (big rubber boot) to the throttle body. It may have a crack on the underside and when you put it in drive and the engine torques to that side the crack opens and causes it to die.

When put into reverse and gas is pressed car goes nowhere but revs up when car is put in drive and revs to 4000 RPM it just inches forward. Any idea why?


If it's an automatic, is there fluid in the transmission? If the fluid is ok, the transmission is bad. If it's a straight stick, the clutch is bad.

How do I set the timming on a 1400 Nissan sentra 1998 model


This is for a 1998 nissan sentra 1.4 engine, start engine and allow to reach operating temp.then turn engine off and disconnect throtle postion sensor connector.

With tps sensor disconnected start engine and increase idle to 2000 rpm three times then release and allow it to idle.

now check timing, timing should be at 6-10 degrees BTDC. adjust as needed then turn key off and reconnect tps .
Good day.7_15_2012_4_06_52_pm.gif7_15_2012_4_07_06_pm.gif

Timing at idle is more than 1000rpm


It appears the car may not be entering tuneup mode. warm up until temp is normal, idle stays below 1000 rpm
2000 rpm for 2 minutes
rev engine 2-3K three times
idle for one minute

turn off
disconnect tps
start
rev 2-3K three times
adjust timing
