I have this problem for quite a bit. The idling speed when engine started cold is between 700-800 rpm. As the engine gets hotted idling rpm increase to almost 1000rpm. If idling is adjusted back, the rpm is starts low (engine vibration felt) at cold start and most of the times engine can not start. When gas pedal is pressed the engine stalls and sounds the engine is choking. My vehicle is a 1994 Nissan van with 2L engine. Am not sure if it similar to Sentra or Altima but it is carbureted.


There appears to be a thermal movement of choke mechanism that comes about once vehicle is warmed up. Check the chock connections, hot water pipe and linkages tight or clear.\015\012gazakat ... Nissan Sentra

When I start my corrado it revs high to about 3000 rpm's then comes down to normal in about 30 sec. It also drops low like it's going to shut off when I stop and take a bit to come back up to a normal idle rpm. Is there anyway to adjust this I recently replaced the idle control valve.


Try replacing the fuel cervo, tripping of rpms mostly comes from faulty cervo. hope this helps ... 1992 Volkswagen Corrado

I have a 2002 nissan sentra SE-R. when the engine is really hot, it dies in idle, the idle is 600 RPM, i guess the idle is too low. So I have to rev it when im at the stop light or double pedal if i make right turn, or if it dies i have to bump start it, i don't wanna ruin my transmission. im thinking about changing the spark plug and the spark plug wire and adjust the idle a little bit higher. any concern about my car issue, please let me know.

Got the same make/model/year, but haven't had that problem. Does your temperature gauge run at half or above when this happens? If so, start with a cheap fix - new thermostat.Another thing to consider is that some of the QR25DE engines ... 2002 Nissan Sentra

Hi guys, I have a 1989 toyota corolla fx-gt, and when i start it up in the morning, it idles at around 1300-1400 rpm, but after a while, drops to around 1100. When the engine is warm, and has been driven for around 30 minutes, it will often idle too low, and stall when slowing down from a high speed, should I adjust the idle speed to fix this problem?

1999 Acura 3.2 TL has 87,000 miles changed spark plugs but starting RPM still low about 500; sometimes it takes two starts using gas pedal. Can you adjust Idle or does it need timing adjusted.


You need to replace your IAC (idle air control valve). The IAC, like it sounds, control the idle of your car. When they go bad they will cause the low idle and stalling. The IAC is located on the throttle body and is usually held on with a coup ... 1999 Acura TL

Aloha, my 96 integra starts up just fine idles at around 1500 rpm as it is warming up than after warmung up begins to have a low idle of 500 to 600 rpm sometimes lower. occassionally even if the gauge shows a steady idle at 750 to 800 rpm visually there is still a little shakey i'm not sure what is causing this. I replaced my coil,sparkplugs,wires,and distibutor rotor. I also cleaned the iacv,checked for vacuum leaks and it still idles low off and on at traffic light stops,...etc. Once I star


I don't know if you did this already, but, you didn't mention a new air filter. A dirty air filter prevents the engine from getting the proper mix between air and fuel that it needs to run smoothly. Very often a new air filter resolves many of the i ... Acura Integra

I have a 1994 Honda Prelude Si non v-tech i recently changed distributor and spark plugs. Before i changed sparks car was running rough it had a lag to take off and sometimes lost power while at around 40-50mph (had to really gas it or would slow) so adjusted timing. After it would just idle at like 300 rpm and couldn't take off at all now it doesn't start gave code 8. We check spark plugs they have sparks, checked compression was like between 120-123 was pretty balanced but low and found theirs


Sounds like the catalitic converter/s are clogged up. This would cause low air flow and low compression. I've seen them so bad that they dropped the compression down to 60 lbs. ... 1994 Honda Prelude

My 2003 Jetta GLX (V6) starts with a very low idle 800-900 regardless of the outside temperature and maintain at 850 or so during normal operating temperature. The idle is too slow to kick-in the charging system and I have to tap the gas pedal to 1500 RPM, otherwise, I will have a Battery light indicating low voltage or Alternator Workshop. I believe the idle should initially be at 1500 rpm, especially when the outside temperature is around 0 degree. Everyone of my cars, idle fast at 15

It seems to only do this when i am stopped or at low rpm. The car remains inoperable until it has sat for a little while and will st

I have a 1999 Ford Explorer with a 4.0L V-6 engine. It had a low idle problem and was diagnosed and repaired by replacing the Idle Air Control Valve. After replacing the valve, I am now experiencing a high idle situation. When the engine is cold, and at first start, the engine idles at around 2000RPM and slowly backs down to about 1200-1500 RPM. When the engine warms up it idles around 500-900 RPM. The engine increases RPM after putting the vehicle into park, between shifting and when the a

Cranks good but cold idle way too low maybe 300 - 400 rpm. Have to keep foot on pedal when cold or may die. Usually dies first time or two right away cold. As warms up don't need to use pedal and won't die . Idle is always too low 300 to 500 rpm even when warm. Runs great otherwise. Good acceleration, no missing. New plugs.
