It's your idle air control valve sticking.

I have a 1999 Mazda 626 5 speed and my rpms seem to always be high weather I'm driving n town, 4th gear 30 mph 2100 rpm, or on the highway 5th gear 70 mph and rpms at 3100. This I'm sure is killing my gas...


check clutch for slipping condition,mayb due to worn clutch disc or a oil contaminated disc or a weak pressure plate not locking disc to flywheel therefore giving u a slipping condition and higher than normal rpms

Transmission problem


This will be a problem with a Engine Speed Sensor, which by having the ECM scanned will indicate the correct ESSCM to install.

Why does my 1996 mazda 626 have high rpms when driving


Make sure you have the trany in "D" (drive) and not in a lower gear like 1,2 or 3. Some models must be in "econo" (not "power") setting for the trany to shift at a lower rpm. It will also get in overdrive sooner.

Car hesitating & rpm reving up & down


Most likely, if it's anything like my old Mazda MX-3, the Mazda engines are VERY sensitive to airflow on the intake side. There is possibly a crack in the airbox or intake plenum (sometimes hard to spot if they are in a "bellows" portion), or not latched in place properly or improper airfilter. Give those a look, looking is free, fixing can be pricey, Mazda wants a lot for a little bit of formed plastic, just to warn you.

91 mazda 626 erractic idle surge when engine is cold


My '91 626 did the same thing. I tested the throttle position sensor, and it was good so that wasn't it. The other likely culprit is the Idle Speed Control valve, or Idle Air Control valve, which is a $500 part new (more than I paid for the whole car). I pulled one off a 626 at the salvage yard and got it for 3 bucks, put it on (it's an easy DIY, just 4 philips screws holding it to the intake manifold), however I can't be sure that solved the problem, since I haven't run the car much since then. It would seem the most likely cause, tho, and a cheap fix if you go used. Other possibilities: O2 sensor or Mass Air Flow sensor?

When I drive my Mazda 626 (97) in high way, at about 110 KM/Hour speed. Sometime the tachometer will suddenly go up and come down (e.g. go up to 4000 RPM or 5000 RPM from normal say 3000 RPM in one or two...


Does your Mazda have a standard trans (clutch), or automatic.
If it's automatic, the tranny might be slipping, and if it's a standard shift the clutch may be slipping. Does the actual driving speed (not engine rpm's) seem to stay the same when this happens? If you are still traveling at the same speed even though the engine speeds up, it's your tranny or clutch. I don't think the timing belt and tensioner have anything to do with this. countrycurt0
