#53 of 68 Re: Vibration front right of car [autonomous] by autonomous Mar 10, 2009 (1:19 pm)
Replying to: autonomous (Feb 22, 2007 11:58 am) I had a similar problem last summer when my PCV went south. My Mazda Protege5 (predecessor to the Mazda3) was basically choking when it was stopped. The solution: install a new PCV (approx. C$350).   Oops. I meant to say EGR not PCV!

Replying to: autonomous (Mar 10, 2009 1:19 pm) My 1986.5 Nissan truck is having similar problems. At a stop sign or red light it idles very low and feels like it is going to choke off. The idle is not right, its either too high when very cold or too low when warmed up. Is this the PVC or The EGR??? This truck doesn't have a check engine light so its guess work as to what the problem really is!! I inherited it from my late father and he didn't do much maintenance on it so I'm trying to get it fixed one thing at a time. It only has 71k miles on it and should last a very long time.

Replying to: wise1 (Mar 31, 2009 5:42 pm) Is this the PVC or The EGR   In my case, it was the EGR, in your case it could be the same or something else. One way of solving this is to get a diagnostic. Consider that the replacement cost for an EGR including labour could be several hundred dollars, you wouldn't want to waste the money replacing it if that did not solve the problem. The check engine light is just a warning signal; a diagnostic pulls up the trouble codes (likely OBD1 codes considering the age of your truck). Good luck!

Replying to: autonomous (Apr 01, 2009 2:55 pm) I have a Haynes manual on Nissan trucks that says that the Diag. code will be erased when the truck is cranked 50 times after the code is first given, so the computer will most likely not have anything on it. And OBD1 are not readily available at most garages in this area.
#57 of 68 not easy to find that stuff by Mr_Shiftright HOST Apr 05, 2009 (8:52 pm)
That is strictly a wrecker resource or some of the bigger swap meets, like Hershey in PA.   I doubt anyone is reproducing these emblems.   Now if it were a Mustang, you could order the entire car out of a catalog.   Also check Hemmings Motor News for Ford Parts providers.
#58 of 68 Mazda 3 08 I New Value 2008 miles 5100 by joem5 Apr 08, 2009 (10:54 am)
when I step on the brakes at times the driver side lock clicks as if to lock. I stoppped to get my mail and the other 3 doors unlocked. Then I started car up and the seat belt alarm did'nt go on. While driving down the road I unbelted and the alarm went on.     Lastly, when parked, if I pump brakes up there is a clicking sound under right side of dash.I've had a rattle in center of dash for two weeks,then these problems stated to occur.                  Do think a wiring harness is loose,or a computer is screwed up?
#59 of 68 2004 Mazda 3 ECT Sensor by jmbeaz May 16, 2009 (2:37 am)
Code P0128 - Possible faulty ECT Sensor. Where is it and can I replace it, or is it a Dealer issue? Replies to this message: cactus6 (Nov 17, 2009 10:05 am)
#60 of 68 cold air intake by marockomole Jun 14, 2009 (12:51 pm)
I want to put a cold air intake on my 05 mazda3, Put all the intakes I have found mount the air filter down by the left front wheel behind the splash gaurd in the wheel well. I have herd somethings about water getting in to it when driving in the rain. Has anyone had this problem. Replies to this message: Mr_Shiftright (Jun 14, 2009 1:06 pm)

Replying to: marockomole (Jun 14, 2009 12:51 pm) I'd never recommend mounting a cold air intake down below the level of your engine. It's not just a matter of water getting in--it's a question of driving through a deep puddle, and having a couple of cupfulls of water sucked up into the air intake. When that happens your engine is immediately ruined. There's no warning and no chance of survival. The piston tries to compress the water in the cylinder and bends the connecting rod---instant engine seizure.   Yes you need a deep puddle and some back luck for this to happen, but it's a real risk.

Replying to: jmbeaz (May 16, 2009 2:37 am) Was that your problem the ECT Sensor? Was it expensive to repair?   We just purchased a 2004 Mazda 3 and the engine light came on yesterday.   The code was the same as yours: PO128 Coolant thermostat condition- low operating temperature   Probable cause low coolant open or short circuit condition faulty ECT sensor   Car drives great and shows no problems at all.
