You have a bad temp sender,if this does not solve the rough idle than you have multiple issues and your idle control valve is not functioning properly try removing and cleaning it.its also referred to as IAC (intake air control)

Periodically, EPS comes on Dashboard ,then steering becomes too hard, this will disappear two to three times re start the vehicle or running few meters and switch off the car and re start the car.


well I can't drive it and see all symptoms.
i can't see the idle speed drop below 800 RPM,. !
if the idle drops real low, then engine shakes, and PS gets weaker.
Id ignore the EPS till such time as all other things are perfect.
ever get an engine tuneup this decade?
low engine RPM , top number 1 cause is owners not servicing their cars. (spark plugs bad tops that list)
if you ignore that, tuneup the engine WILL misfire and RPM will drop and P/s (means power steering)will get weak (the assist is pump driven) and then the engine can stall.
i bet you also forgot to say the steering got weak
park or coming to a stop with foot off throttle.
do the head lights dim as this (bad) happens?
can you use your right foot to keep RPM above 800 and save stalls or near stalls?
IF RPM is ok, ?then check the fan belt next. (slips)
or buy a new on, my guess is 11 year old belt is kinda hopeless case.

Toyota corolla hatch 2002 idle at 2000 rpm when


All the above is normal , except 2000rpm is a little high at idle . can be adjusted down to 1500rpm. the computer adjusts the engine speed . in drive the transmission loads up the engine idle drops to 1000rpm . in park engine unloaded rpm increase all normal.

Loud idle running hot in park but not in drive


double posted
post RPM in both modes,
it must be the same
the ISC idle controls system controls idle at all times.
post RPM. 800 is normal. the exact valve is in the FSM
and posted under the hood in USA.
no country stated in 4000s posts so.... well, gee....
here, open the hood, look up, see EPA vacuum map
that is also the the engine size and type , and most state the normal
hot RPM clearly there, and is in the FSM.

here is the acid test. hot.
in park hot, rpm 800 if not the ISC fuction is dead
"idle speed controls"
good? yes.
then select drive. if RPM drops ISC is malfing.
now back to park. (all this is in the FSM to read)
now 800 hot. you turn on all heavy electrical loads
the rpm does not drop. Head lights + heater fan, and defrost.
all these test he ISC, if it fails its bad.
what does bad mean, that means its out of control
and you do further testing to find the reasons.

vast reasons.
Ill name 3:
intake air leaks. aka vacuum leaks.
ISC valve dirty , clean it.
throttle cables , misadjusted.
cold start air valve stuck open hot.

My 1997 ford f150 starts fine, but has a high idle while stopped usually about 1200. Sometimes the idle will drop to about 400 and the truck almost stalls. Help?


To be honest no idea with my head under the bonnet and having a play to see whats wrong ,could be anything from a vacumn pipe to faulty sensor .

My car slams when put into drive. is it the idle


Yes, sounds like the idle speed is too high. If you keep driving like that, you will fry the torque converter / turbine. Since idle is computer controlled, you will have to take it for service tune up. There is one possibility that the rich, high rpm idle used for cold start is not disengaging properly after the engine warms up. Air conditioning will raise the idle speed by a couple hundred rpm, so avoid using it until you have the problem fixed. BTW.....warm engine rpm in idle, and neutral should be around 700-800. Anything over 900-1100 will result in a hard shift into 1st gear and dragging at stop lights.

When bought engine idled @ 800 rpm when warm, now engine lite is on and engine idles rough @ 500 to 600 RPM. Replaced rack and pinion, power steering, checked wires, replaced sparkplugs, # 1 plug was in...


could be numerous reasons. this is your best bet take it in to a mechanic and have your engine codes scanned. it is a minimal charge, some even do it for nothing it only takes 10 minutes.this will point you in the right direction.

2000 Ford Escort ZX2 hot, idles ruff and sounds like a vacuum leak


Check your IAC,, Idle Air Control solenoid. It is attached to the throttle body and controls the air flow at idle by bleeding air into the throttle body.
