Probably the fuel filter or pipe is partly blocked. When it runs at idle it has inough fuel. When you push the pedal it cant suply inough fuel and the engine sucks the fuel sistem dry, thats why it is so hard to restart the engine. Ewery time, when you turn on the egnition, the fuel pump in the tank is working only for three or more seconds. Because of blocked fuel pipe, or filter, it takes more time to pump up the fuel in the sistem. Chek the fuel filter and blow the fuel pipe.

7.5 l engine. Starts well but idles a bit roughly. Check engine light illuminates intermittently but does not stay lit constantly. Thanks!


If you have a check engine light the best thing is to read the codes and find out what the problem is. Many shops like Aamco read codes free.

Idle is high at start - 1800 rpm. Seems like excessive white smoke from exhaust. Put into reverse and back out of driveway it has a regular shudder (bump bump bump) but not hard metal grinding sound.....


white smoke out of the exhaust would be a sign that it is burning coolant... if it goes away after it warms up, it could just be condensation inside the exhaust pipe. 1800 rpm is a very high idle, maybe have your IAC motor on the throttle body checked... check engine light? if so have the code read at your local auto zone.

Revs upto 4000 rpm in idle and while driving too ! all by itslef.


mcdevito75 here, Sounds like the idle speed motor or the idle speed sensor is no good. Your local shop can check this out for you.

RPM indicator problem


mcdevito75 here, Sounds like the Cold Idle valve or motor is bad, The fast idle valve or motor depending on your car allows the engine to run a bit faster when cold, the A/C compressor is also hooked up with a device that allows the engine to run a bit faster to handle the load of the A/C compressor or your cars air conditioning, I think your problem is a faulty cold idle valve / motor, have your auto repair shop check it out and replace.

Car idles at 2200 rpm. Slight miss at normal speed and idle. Bad MPG. Somtimes idles normally. Replaced plugs and wires. Engine light goes on and off.


Sounds like a bad vacuum leak. Check all the engine vacuum hoses, make sure none are broken/cracked/disconnected/missing.

On my 2001 olds aurora 4 liter engine when I come to stop at traffic light low oil pressure light comes on until I bring RPM's up,is there a way to increse idling?


Sounds like your oil pump is bad - I'd have that checked. You can adjust throttle via the screw on the throttle line (look for the intake and there should be somthing resembling a bicycle cable going to the round throttle body). Tighter = higher idle. Fix the cause as soon as possible as this can destroy your engine quickly.

Carburettor adustment on 1995 mitsubishi starwagon


If you have a carburator still then you need to know more.
screwdriver method on feel/rpm gauge
Proper exhaust measurement.
Run her up to 650 rpm idle start adjusting mixture screw until max rpm obtained. back out a bit too be lean. Ajust Idle screw again for 650.
Turn on appliances as lighting and airco. If engine starts/tends to stall, vibrate increase the idle a bit more.

You are not ready with the engine if not doing ignition settings and valve clearances as well, etc.

Oil Pump light flickering + rough idle on 1996 Nissan Maxima


Sounds more like the Throttle Position Sensor or another sensor is letting the engine RPM's drop too low. When the RPM's are too low, the oil pump is not pumping enough oil.

Engine miss above 2000 rpm


sounds like a valve problem. check compression running and non-running. valve sealing at higher rpm is usually a valve spring problem is if runs ok at idle.

Engine idling varies depending on light or aircon is on/off


dude its normal for first start or cold start that the idle is ok but it must high than normal... its normal because the engine is warming up it self... when it gets warm, the idle speed will return normal idle... your engine is 1200cc, it has not much HP for a great load... and i know its a carburatored engine and its an old engine, your head lyt and a/c fan and aux fan and all the electrical system on your car, uses the HP of you engine and its a lot of load to the alternator driven by the engine to generate an electricity they need and thats why the engine rpm speed lowering down to dead and its shake. thats why when you use your lyts or all electrical, you engine is weakening... the best remede is adjusting you idle speed... its located behind the carburator.. its a small black knob.. just make a twist each eighter way and you'll find out if your idle rpm speed ts incresing or decresing.. just increase it and try opening your lyts and other electrical, if its still shaking then adjust it a little more
