#1348 of 1380 Re: High Rev on idle on hot days! [aerosim] by mathieuverron Jun 29, 2009 (10:22 am)
Replying to: aerosim (Apr 28, 2009 5:09 am) Hi, my mp5 2002 150,000km is doing exactly the same as yours did last April. Could you please tell me how it did get resolve? My Mazda dealer just called me today, June 29th, to tell me they don't know what is going on. I had the EGR valve replace 1 year ago, but since the Check Engine light doesn't come on, they say it is not the EGR valve this time. Thanks for your time.

Replying to: mathieuverron (Jun 29, 2009 10:22 am) Well, I've been avoidind the problem by not getting jammed in traffic when it's more than 25celcius outside... I will bring the car to the garage in a couple of weeks to change the timing belt and i will let know my garagist the problem. Hopefully, he is going to fix the problem (which I doubt) or I will keep avoiding heat trap. Anyway, since April, it didn't really occur again, but I wasn't jam in traffic for more than 15-20 minutes on hot days. I'll give you an update after my visit for the timing belt. In the meanwhile if someone find a solution, let me know.   THX
#1350 of 1380 Sport Mode Auto Trans Issue by 03p5owner Jul 20, 2009 (2:45 pm)
I have a 2003 P5 with a 4-speed sport mode automatic transmission. The transmission suddenly began operating strangely. When the gear selector is in "D" the dashboard indicator shows "M" for manual mode. The transmission does not upshift or downshift when in "D" now. When I place the gear selector in the manual mode position the dashboard indicator still shows "M" and the transmission shifts fine manually. I'm wondering what might cause the automatic mode to suddenly malfunction.
#1351 of 1380 Whine at certain speed by 1bandit Jul 23, 2009 (10:56 am)
I have a whine coming from somewhere that starts at about 30 MPH, the trans seems to be shifting ok. When I take it out of gear and coast it still makes the noise. Any suggestions? 83,000 miles Replies to this message: gretsch6120 (Jul 23, 2009 12:18 pm)

Replying to: 1bandit (Jul 23, 2009 10:56 am) Are you sure it's coming from the engine? Is it definitely mechanical? Not old wiper blades for instance? Or something else more cosmetic.

Replying to: iamz (May 24, 2009 8:48 am) Realized, I didn't thank you for the tip. Feel like a bone-head I didn't see the diagram but much thanks nonetheless!   -A
#1354 of 1380 Over heating - help diagnose by gretsch6120 Jul 23, 2009 (12:33 pm)
2002 Prot5 - 125k Odo. Car is overheating when it's warm outside and on the highway driving at 70+ for 20min. or up a long hill. When it's cool, low 60's, there doesn't seem to be a problem. Water pump, thermostat, and coolant flush were all done in the last 15k.   I'm beginning to think we might have a small hole in the head gasket? Mazda dealer here wants $100 to do a compression test.   Any opinions? Replies to this message: autonomous (Jul 23, 2009 2:23 pm) iamz (Jul 24, 2009 4:11 am)

Replying to: gretsch6120 (Jul 23, 2009 12:33 pm) Car is overheating ... Mazda dealer here wants $100 to do a compression test.   As in your temperature gauge needle goes up into the red? Do you get any other warning signals? How are your hoses to and from the radiator?   The compression test may not be a bad idea if it helps locate the source of the problem.

Replying to: gretsch6120 (Jul 23, 2009 12:33 pm) I don't feel that a head gasket leak would cause your engine to overheat unless you were losing tremendous amounts of coolent in the process. Are you losing coolent? Does your oil look contaminated or are you seeing white clouds of vapor coming out of your exhaust? Those are things to look for with a head gasket failure. A partially blocked radiator could cause overheating. That can be difficult to diagnose though. And as autonomous mentioned, are you sure the car is overheating?

autonomous, iamz,   >>As in your temperature gauge needle goes up into the red? Do you get any other >>warning signals?   This is purely judging the temperature gauge needle goes up. No other warning signals - no engine light. (We've joked, it's probably the gauge.) How else can we or a mechanic test this?   We don't appear to be losing much coolant. It's not being eaten like I've heard tends to go hand-in-hand with head gaskets.   There doesn't appear to be any coolant in the oil -- Looking for white film around the oil cap as well as smelling cap and dip stick.   >>How are your hoses to and from the radiator? No idea, what should I look for, cracking? Bad connections? Anything specific?   I'll look for the vapor out the exhaust, but nothing has seemed out of the ordinary.   Partially, blocked radiator... hmm. There does appear to be radiator gunk in the coolant reservoir. Maybe another coolant flush would unblock things?   Appreciate the replies. Let's keep this going if you guys have time.
