Mazda - Tribute :: Clogged Exhaust Systems That Make EGR Valves Blow Up
I have a Mazda Tribute, 2005, with clogged exhaust systems that make the EGR valves blow up. Definitely due to a problem with the exhaust system, but I can't find where it is. I've replaced one of the catalytic converters and checked the other, but it didn't work, my next guess is the muffler or the manifold. Engine occasionally misfiring due to a vacuum leak that prevented the intake manifold to provide even oxygen for full combustion. The extra gas when into the exhaust system a burnt up one of the cats and left a clog somewhere in the exhaust system. If is the other cat it's a $650 part.
View 6 RepliesToyota - Corolla :: 2002 - Ticking Valves At Past 50 MPH While Motor Is Unloaded?
I have a 2002 Toyota Corolla CE with 160,000 miles on the odometer. While driving at highway speeds (50+ mph), if I let off the gas ever-so-slightly, an audible ticking (like the sound of a sewing machine) begins. It immediately goes away as soon as the motor begins to decelerate or accelerate again. It ticks the loudest while the motor is directly in between accelerating and decelerating, while I am trying to maintain the speed I am traveling at. The sound started 6 months ago and was almost unnoticeable, but has gotten steadily louder the more I drive it. From what I have already researched, I believe it might the valve lifters needing to be changed, but wanted to get a second opinion.

View 5 RepliesToyota - Corolla :: 2000 - Cleaning Of Valve / Throttle Body?
Car is 2000 Corolla with 60k miles that sometimes has a low idle (sometimes) when driven for the first 15 minutes early morning. Especially when accessories turn on, the RPM drop suddenly to 600 and recovers to 623 then back to 650rpm. After 15 minutes, everything works fine (normal 650 rpm)....my guess is the IAC Valve/throttle body needs cleaning.
What exactly do I need to tell me mechanic? That both the IAC Valve and throttle body needs to be clean? Also, after "cleaning it using a spray"....should he wait till the "spray dissipates"? What happens if it goes inside the engine?

View 4 RepliesToyota - Corolla :: 1995 - Engine Dying While Braking?
I drive a 1995 Toyta Corolla. Two things that I should mention that may or may not be relevant. I have a history of electrical issues (I've replaced my alternator 3 times) primarily when it has been wet outside. I have also noticed smoke under my hood. I was initially scared this was an engine issue, but my brother assures this is due to a power steering leak
The issue at hand:
For the last couple days I've noticed a few things worth mentioning. First my brake light has come on a handful of times, however oddly never when actually braking. Secondly, my enigine will sometimes but not always stop running when I brake. At this point all my electrical systems still work (lights etc.) and all the lights on my panel come on (which I understand is normal if a car is on but engine not running). Lastly, my car has never not stopped, but it has been for the lack of a better term "mushy" for a couple weeks.
When I go to start the car again after this engine stop, sometimes it will immediately start, sometimes it will struggle (rewr rewr rewr) but then start, sometimes it will struggle and go to battery noise ""click click click"", and if we start getting the battery clicks it stays there until jumped.
My brother today went and checked my battery with an multimeter, and he states that my battery is both maintaining a charge and charging (He told me to tell you he got Cold not started 12.3 volts, car running 14.48).
Toyota - Corolla :: 1995 - Started Shuddering While Going Up Hills?
95 corolla 277k miles. 4 hours into a long trip went over a huge bump and the shocks seemed to "bottom out". Like they compressed as much as they could. Pulled over half hour later for a break.
After that drove rest of way home. Car started shuddering and slowing down going up a hill. Had to floor it just to get it to be 60 mph. Hill wasn't that steep. Seemed to do ok on flat parts.
Was a little low on gas so pulled over to fill up. Noticed car idled very roughly felt like it was going to stall while pulling into gas station.
Gas cap was a little loose. Didn't hear the whoosh of the vacuum you usually hear when undoing the gas cap either.
After that it seemed to be a little better going up hills. I drove it home, and a day later drove it and it seemed to go up hills ok.
It still idles very weirdly, roughly and like it's about to stall. While driving it sounds ok.
I was thinking fuel pump but now i'm not sure. It might be related to the gas cap, maybe the bump loosened it.
Toyota - Corolla :: 1997 - Valve Cover Leak While Recharging Battery After 2 Years
My uncle has a 1997 Corolla that has been sitting on his garage for about 2 years. We jump started the car and after a while recharging the battery, we saw fumes coming out from the engine. I then noticed that there was oil all over the front of the engine.. From what I have found in google it seems that this is a valve cover leak. How serious can these be? Are they easy to fix? because my uncle is thinking on calling the junkyard.
View 13 RepliesToyota - Corolla :: Sputtering / Rough Idle After EGR Vacuum Check Valve Replaced
I replaced my EGR valve vacuum check valve, but now started getting sputtering/rough idle. I'm pretty sure the direction of the vacuum check valve is correct, but I tried both ways to be sure and still got the sputtering at idle.
The old vacuum check valve didn't give me the sputter. I only replaced it because it was melted and I'm not sure it was working. I included a photo of it. It's orange and black.
Lexus SC430 :: Clogged EGR Valve - Code P0430
Just read that a clogged EGR valve is common and reduced performance and increases emissions. Need to clean this valve? Where is it located?? Just noticed tonight that there is not a lot of suction from my vacuum lines and I wondered if this is related. Plus I have a p0430.
View 3 RepliesToyota - Corolla :: 1995 - Driver Door Opening Intermittently
My 1995 corolla door would not close. I looked and discovered that the 3 screws holding the door lock mechanism in place were gone. I went to the hardware and bought 3 new screws and installed them. The door shut and now it will not open at all. It was opening intermittently, so I bought shorter screws and put them in and now it will not open at all. The screws are flush with the door. The door is not stuck, you can feel that it is locked, so forcing it will not work. Climbing in and out over the passenger seat is quickly losing it's appeal. Monday I am taking the door apart from the inside.

View 17 RepliesToyota - Corolla :: 1995 - Transmission (AT) Shifts Into Neutral While Driving
My 1995 1.8L Corolla wagon (230K original) automatic transmission will shift to neutral while I am driving. It will do this at any speed. It lasts for one to five seconds. Otherwise it runs and shifts perfectly . It does it on level or graded roads, maybe one to five times per week. I no longer feel confident to drive it. At first I would be driving along and the speedometer would go to zero. This would last for one to three miles. Then, after this, the speedometer would go to zero and the overdrive light would go on/off, and the transmission would shift back and forth. I changed the VSS but it did not fix the problem. Now it does the same again, only the transmission shifts to neutral.(The lever stays in Drive) This lasts for one to five seconds. Moving the shift lever during this time has no effect.
View 5 RepliesToyota - Corolla :: 1995 - Misfire Around 3000 - 3500 RPM Only When Warm
Car: 1995 Corolla 1.8L automatic
Symptom: misfires around 3000-3500 RPM only when warm.
I have replaced the following:
-Spark plugs, wires, cap, and rotor
-Ignition coil
-Fuel filter
-Poured some quality fuel system cleaner into the gas tank
The car stutters when accelerating in any gear hard enough to reach the engine speed that the misfire occurs at. It doesn't backfire, it just misses... I am confused since so many of the misfire issues I know about that are RPM specific are spark-related.
I have considered cleaning the injectors, but don't want to go through the hassle to remove and have them cleaned unless I really have to. Checking if hunch on the injectors is correct? Something else?

View 6 RepliesToyota - Corolla :: 1995 DX - Engine Just Stopped While Driving On Highway Then Would Not Turn Over
The car's engine just stopped while driving on highway, then would not turn over, nothing.Took for repair, said battery had bad cell or something, still under warranty, replaced.Fixed a few other things that were overdue, spark plugs, wires.
Okay. Next day, took the car on a few city driving short trips. While going across town on hot 85 degree day w/ ac on, it died again. Don't remember any lights coming on, didn't last time either. I think the AC died first then car died. Wouldn't make a peep. Right in middle of heavy traffic. When police came couldn't even steer. There might have been a slight weird noise which I thought was the ac making trouble right before it stopped, can't describe it really.
Had it hauled to shop again. It runs fine for them so far. They are still working on it.What in heck could it be? All belts were replaced a few years ago, car has always run well, never any major repairs just maintenance. It has about 133,000 miles on it. It has a clutch.

Toyota - Corolla :: 1995 - Engine Missing Sporadically Especially When Idling And Cold
My 1995 Toyota Corolla DX with 180,000 miles is missing. It was missing intermittently, especially when idling and cold, and especially when I drove short distances to run errands and then restarted it. It got to the point where it was missing even when warm, and would stall out when idling (always restarted eventually). I took it in to a shop, and they replaced the spark plugs, spark plug wires, ignition coil (which was fried) and the distributor cap and rotor.
All of the low speed and idling problems are solved. However, it now misses intermittently when I drive on the highway, only when giving the car gas at speeds of 45 mph or higher. It doesn't miss when I am coasting, regardless of speed, and doesn't miss at all under 45 mph. This car drives too well under 45 to be headed to the scrap yard yet.
