Question about Mazda 2004 Mazda3

Open Question

Engine 60k on it. Check engine lt stays on. Got gas fume leaks fixed--as soon as I got it back from the shop, it starts bucking. Cleaned throttle body, still hesitates and now wastes gas, no power,vvt

Has aftermarket cork sport intake. Old manifold was destroyed by spouse with reciprocating saw :( Mechanic says intake is the cause of check engine light staying on, because the MAF sensor is getting tripped. I don't have the code is on the service receipt, which I conveniently left at home Suspicions are airflow leaks. I haven't gone back to the mechanic this time since every time I get my car back something else breaks--and he seems overwhelmed at the moment. I really don't want to sift through another junk yard for intake parts.... Although I also don't want to keep wasting gas. All the get up and go in the throttle got up and went. Insights? Opinions?

SOURCE: AT Warning light and Check engine light both turned on

Unfortunately Mazda didn't have the best transaxles out there. First you have to find out what the code is. If the shift solenoid acts up, it will turn the "check engine" light on and well as the AT light. Take it to a shop that is able to scan the codes and let you know what it is. If it's a shift solenoid code, in which that's what I'm expecting, check all the connections to the trans. at the plugs. Look for any frayed wires, burnt or dirty plugs, and any pins that may have lost contact with the sensors on the trans. If all of them look good, take it to a trans. shop for further tests.

SOURCE: I have a 2006 mazda

I wouldn't replace the plugs, just yet. This sounds like the vent solenoid. They are usually around the fuel tank and sometimes located on the charcoal canister, Which I believe is where yours is. Test it with 12 volts it should click. if it doesn't then replace this. On newer cars like yours, when the vent or purge solenoids malfunction, they will pop an 02 code. If the solenoid clicks then check the wires right at the plug . they tend to break there. And the gasket your looking for is the intake manifold gasket. And looking for the solenoid, look under the emissions and EVAP systems.

My 2008 Dodge Avenger wont turn over. It cranks and gives a little rumble like it could start but lacking something. Almost as if it did start, it wouldnt stay on long at such a low idle without giving it...


You could have a small (or big....) gas leak in your fuel line (check if you smell abnormal gas fumes) or a defective gas pump. Try this to check: put the ignition key on "accessory" (like is if your in the car but just want to listen to the radio with engine off), this will active the gas pump to "pre-feed" the engine with gas with the correct amount (try it at least 2 times) then try to start the engine.....good luck!

Note: It did happenned to me and it was a leak in the gas line.

Fumes inside 1998 subaru forester


I had a 2000 with leaking fuel lines. There are a few molded rubber lines. Check the condition of the rubber and the hose clamps. If they are wet, you have a leak. When replacing use the good clamps that you can tighten with a nut driver

0441 the most common fix for this code in chrysler/dodge vehicles is to replace the leak detection pump / ldp -----other areas to check would be damage / restriction in evap line / canister---faulty purge solenoid or connection damage or resistance in line -bad vacuum switch

DPFE changed out burning smell


Check the fuel system, the pump and the fuel pressure regulator or Mass Air Flow Sensor. Evaporated emissions are the fumes that your fuel gives off. The pollution control system pulls them back into the intake to burn them off when you are running your engine. There is a vacuum line that is leaking between the fuel tank and the sensor that detects this or your gas cap is loose or leaking. It could also be a bad sensor which detects vacuum pressures from the tank. If everything has been check, then check inside the throttle by pulling off your Air pressure Intake then open the throttle by using screwdriver or any tools than can push in one the fuel control line to open, which is attach on the left side of the throttle. and if you look straight inside, you will see three hole. Then look by the bottom and you will see the two hole cover with black burned Oil. This means your fuel mixer (Throttle) is not pushing out air properly it gets clog , and the only way to get out is when you push the Gas peddle which is the burned gas will come all the way out to the Air Intake and it will circulate to any open area. If I was right about this! Your solution is to buy a Air Intake Cleaner or Carb-Throttle Cleaner. with the engine OFF, spray inside the throttle by using the red straw and point it to clean the two black clog hole. then wait for a about10 minutes or more to dry up cleaner after spraying the inside throttle. When you start the engine, black smoke will come out to the muffler. No worry this is normal to the engine, means the cleaner is burning and working to get out. Without cleaning the throttle body, the engine will soon stall, or stop without any giving warning light, because this means your A.C. Pressure Clutch and Idle Pully barring are NO longer working properly and maybe totally wormed out. You may also change the throttle position sensor. and check all your Gas and Oil Intake Hoses for a leak. hope this will help to solve your problem. P.S. You can also spray the Intake cleaner to your Intake Mass Air Flow Pressure Filter before putting it back to the throttle body.

Gas fumes inside and out side the car when it is hot outside


Try having the area that the hose was disconnected from steamed cleaned, or go to a car wash wash and spray the area. It might help, that is if you already haven't done so.
