Dumbfounded at what the problem is?!
Ok back in June my car stalled. Dealer says plugs...wires...and coils. All that gets done and car stalls again in July. This time they say do the engine decarb. Did that and all was good until yesterday. Stalled again 4 months later!
Ok so i thought maybe this is a catalytic converter problem but i just went through emissions here to get my tags and passed fine. If that was the problem i wouldnt pass emissions would i? So i really just dont know what it could be and why its only happening every now and then? Back in the summer i thought it was due to the heat but yesterday was only in the 60s here and i had been driving through town just fine until it suddenly decided to do it. Then afterwards it drives just fine? Its very strange how randomly it occurs. Always happens when coming to a stop...the car starts to jerk and i instantly know its trying to stall. It feels like its clogged up or something cuz even when i punch the gas to try to keep it from stalling its as if im not even pushing the gas. So im gonna just take it in and say keep it til u figure out whats going on i guess and rent a car. Nothing worse than stalling out in traffic in such a nice car! I love this car I just need to trust it! |
Might be something with the fuel system or the engine is on its way out.
Have them do a compression test. |
They say they have done the compression test. I was actually thinking if it was the fuel filter or something fuel related since it feels like its chocking itself out ya know?

Start with the simple and cheap "fixes"; 1) Make sure your air filter is clean. 2) As stated, clean the MAF sensor. 3) Also clean your e-shaft sensor and reset the profile (20 Brake Pedal Stomp Procedure). 4) Make sure your spark plugs are tight and the plug wires are firmly seated on the plugs and coils.

62k miles...it flooded once last January and was towed to the dealer. No mods are installed. Cleaned maf sensor and got new air filter in January. Spark plugs and wires are tight and were double checked by my friend. I did the decarbon myself using mazdas cleaner but I think I'm gonna do it again cuz the engine had cooled down before I got the treatment sucked in. No white smoke came out the tailpipe at all when I did it back in July.

Something else to add I use to get about 260 to 280 miles per tank and now it's about 220 to 240 and I have always used premium gas.

I fogged the entire neighborhood when I decarboned mine. :lol: |
But how could I pass emissions if I had a bad cat?

the cat is 2 parts. the first section followed by the O2 sensor, followed by the rear(backup) section. the first section is failing, which you have determined because this causes the O2 sensor to report a CEL. but the second section of converter is still doing its job and you pass the sniffer(assuming its sniffer only) not saying this relates to the OP, or that its realistic, but it could happen |
I do not have a cel
|
Oh and when they do emissions here they plug in to the computer so it does not involve a probe being stuck in the tailpipe anymore

I will def keep this updated in case other people out there are having the same issue! |
UPDATE : So it tried to stall again today....and when i got home and put it in park i could hear the engine choking. I got out of the car and listened to the exhaust and u could hear it pop and at that moment is when the engine would choke. So thats def a misfire right? Has to have something to do with the fuel system i would think because i have new plugs...wires...coils...did engine de carb twice...cleaned MAF ...new air filter...i mean what else could cause the misfire?

Did you clean the e-shaft sensor and perform the NVRAM reset like Ray stated earlier?

Spend the $100 and get the compression test down. All will be revealed.

Why would it cost to get a compression test? Wouldnt that be something thats covered under extended warranty?
