    06 mazda 3 2.0L engine idle intermittently goes up and down while driving or at idle!

    Update and a question. Well so far so good but as this was intermittent issue I'm not sure it's really fixed. I have a question on scanning the car. My issue did not set of a check engine light and I also have a code reader/erasor. Would a dealer diagnostic scan dig deeper into my issue and...

    06 mazda 3 2.0L engine idle intermittently goes up and down while driving or at idle!

    Well topped off coolant tank and bleed off any air with passenger side raised. It only took about 0.4 gallons of fluid to get to max level which is bascially just what the resevoir holds so I'm skeptical that the low coolant is my issue with rpms as it was not low by very much IMO.

    06 mazda 3 2.0L engine idle intermittently goes up and down while driving or at idle!

    I can certainly follow that logic. Perhaps when the idle speed kicks up for cold idle map by false temp sensor reading that would causes the water pump to run faster due to increased rpms causing a coolant surge within the engine. After that surge the temp sensor gets submerged in coolant...

    06 mazda 3 2.0L engine idle intermittently goes up and down while driving or at idle!

    Thanks for the reply and tip for air bubbles. I have heard of that before for removing stubburn air pockets. I will have to investigate where I lost my coolant. The cycling up and down of the rpms happened when the engine was fully warmed up both times. The pattern of rpm cycling was like...

    06 mazda 3 2.0L engine idle intermittently goes up and down while driving or at idle!

    Just noticed coolant level is way below the minimum level while cold. Will fix that. Is there a sensor that could be acting up due to low coolant level that would effect my erratic rpm issue ?

    06 mazda 3 2.0L engine idle intermittently goes up and down while driving or at idle!

    Forgot to add this car has 126000 miles. Any input appreciated as I'm pretty handy with wrenches and voltmeters. I'm not sure where to start as this doesn't sound like a normal idle probem like a IAC valve or dirty throttle to cause such a wild rpm pattern. Also the second time this happened I...

    06 mazda 3 2.0L engine idle intermittently goes up and down while driving or at idle!

    This is a completely stock 2.0 L with no recent engine work. Twice in two weeks while driving the car the engine rpms have gone out of control with no codes. While driving at 40 the engine rpms started swinging up and down from 2500 to 1500 no foot on the gas but the car was trying to...

    DIY front wheel bearing/hub replacement?

    The black ring on one side of the bearing needs to be installed towards the ABS sensor or stud side. Here is a link to another thread http://www.mazdas247.com/forum/showthread.php?123743896-ABS-light-on-after-new-wheel-bearing-hub&p=4602791&highlight=#post4602791 Greg

    06 mazda 3 intermittent no crank

    Update Yes, I could under stand that but that was not my case as I could hear my fuel pump come on. It's been starting fine now since the neutral safety switch replacement.

    06 mazda 3 intermittent no crank

    no start update Did the starter wire repair which did shows signs of corrosion but it didn't fix the problem. Noticed the P indicator did not iluminate green when car would not crank. Went to dealer and purchased a nuetral safety switch $ 65.00 which is called something else by Mazda. Mounts...

    06 mazda 3 intermittent no crank

    Just found a service bulletin on this Bulletin 01-037/08 Subject: Starter motor will not crank and engine does not start (intermittently). Sounds like they have a known problem with corrosion on the wire to the "S" terminal of starter.

    06 mazda 3 intermittent no crank

    93K auto 2.0L - 3 times in the last week the car will not crank over. 1st time we thought is was a fluke. It acts like a neutral safety switch is not being made to engage starter solonoid. Or possibly starter solonoid is failing. If you play wih the steering wheel and move the shifter around...

    DIY front wheel bearing/hub replacement?

    Glad you got it done. Agree on the knuckle comment but getting the old race of the hub was tricky too without ruining the hub ( I used a cut off wheel & chisel). Otherwise pretty easy as long as you don't put the bearing in backwords on ABS cars like I did. Paying someone to press the bearing...

    ABS light on after new wheel bearing/hub ?

    Took everything back a part and yes I installed the bearing backwords. Installed a new bearing with the black ring towards the sensor. ABS light was still on after starting up the car but it went right out after I backed out of the driveway and went forward a few feet. Also now that the abs...

    ABS light on after new wheel bearing/hub ?

    Watch your wheel bearing orientation Good call "TheMAN". Just got back from Mazda dealer. Purchased another bearing and didn't notice it the first time around as I was not looking for it but one side of the bearing has a black ring on what I would call the dirt seal and the other side of the...
