SOURCE: engine stalls at stop lights and stop signs

sounds like the torque converter lock up might not be disengaging. You might also want to check for engine vacuum leaks. Does engine idle smoothly when in park or nuetral ? if the idle is good I would suspect torque converter problem.

SOURCE: Engine RPM surge in idle

I was kind of surprised to see your post, I have not run across this problem in my shop yet, maybe just demographics. 1000. bucks to do this job seems high, maybe shop around. I did a little checking on the net and it does seem to be common. I found a very good article, even if you don't want to do it yourself, it may give you some ammo, and help you understand what's involved.

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

Battery barely starting car, engine only rev to 2500 rpm


Loose or corroded battery cables, Loose fan belt not turning alternator fast enough, Bad alternator, check the battery with a Voltmeter, voltage with engine stopped. should be slightly over 12V Start engine and check again.. shoiuld be over 14V. this is if the alternator is putting out a charge. Chech the output at the alternator. the BATT connection. usually a larger red wire. should be 14V+ with engine running. Since the A/C works fine with the engine running.. I would have the battery checked.. sounds like bad battery.

Rpm does not drop below 1000


No,only on carburated engines it,idles down to the set point,on yours,it's fuel injected,pushing gas pedal won't kick idle down,should go down after a certain amount of time,does it automatically,If you start and drive a 5 mile ride and stop at a stop sign,it should idle at it's set point if there's no engine problems,which may be.5 to .7 on your tac.When you normally first start,it will idle between 1000 to 1200 rpm's,don't push on gas,let idle say 15 seconds,put in drive and go.

when the check engine light comes on there's normaly a code stored telling you what sensor or other part is malfunctioning. If you go to a parts house some of them will read the codes and then you can replace the part. I know auto zone does this.

I am loosing oil in my 2006 Rav4 my oil light comes on after 2500 miles of driving my car after an oil change.Toyota is saying you consume 1 quart of oil for every 1000 miles. My Rav holds 4.5 quarts of...


I see you have a four cylinder since it only holds 4.5 quarts.
2006 manual confirms your oil consumption is within allowances. Just check oil every time you buy gas like the manual reccomends. Do not over rev engine or accelerate from stops at max capacity of car as these can increase oil consumption.
