Well, you need to tell us the part numbers that your boyfriend installed.
Somehow, I doubt you got the wrong parts, but it is possible.

Mazda said I must use factory oem plugs and factory oem wires. We bought ngk iridium plugs and ngk wires, which are factory replacement. I can give you the part numbers tomorrow. They also said that's the reason the car still stalls, is because plugs and wires are wrong. I am beginning to think they are not wrong, they just want $300 of my money.

Don't cave in. They are making a money grab. NGK is OEM!

Thank you thank you they are damn persistent but we are not caving in. I just hope they're not cutting any corners when it comes to figuring out what's going on with my car.

unfortunately thats the one given situation when you bring your car to a dealer :(

DAMN, this has been going on for a while, im sure there is someone nearby to help you. Try posting in the regional forums to see if anyone can come by who is knowledgeable???

bingo

Sounds like you need to take your business to a different dealer from now on.

BC.

tell them the reason they were changed is because you were still having the same issue AFTER they left the old plugs etc in. Also tell them that you do NOT HAVE to use OEM parts. since they are trying to charge you for the parts the Magnusson Moss act explicitly say you are allowed to use equivalent spec'd parts.

now can you tell us the part numbers for the parts and wires your boyfriend used?

Terry, Eric. Posts move to their own thread here: https://www.rx8club.com/trouble-shoo...rouble-237807/

Kinda rude to derail the lady's thread with your own questions. She hasn't gotten a resolution yet, and trying to answer you both could get confusing. This keeps it clean.

Thank you

Boyfriend forgot the plugs and wires packages at his job, so I'll make sure to get part numbers tomorrow.

This is getting ridiculous. I have had nothing but problems since I got this POS.

Today Mazda said hot compression test is good. They also said everyone there is pointing at the plugs and wires he put in. Apparently they believe that's why the car is still stalling.

They said since I don't want to pay $300 for the plugs and wires they can get OLDER plugs and wires that are BETTER than the updated ones. Does this make sense to anyone?!

On the bright side your compression is good!

The dealer is trying to screw you there is no update. There could be a million things wrong with your car, clogged fuel filter sock, ess profile issues, bad fuel filter, bad maf/dirty maf, failed/dirty fuel injectors, extremely dirty air filter, possibly issues with SSV or VDI valves and solenoids.

Some of those might not cause stalling issues, but if the conditions are right they could. Make sure the dealer monkeys put all your plugs and wires in the correct order.

Yes but I'd rather have a new motor at this point. Sick of dealing with this. And hopefully the dealer monkeys, haha, know to put those things back in the correct order.

That's also what makes me worry...them not finding out what the problem is.

If you can deal with it for another couple weeks, I will be headed to MD anyway and can try to meet up with you with my tools, spares, etc... see if I can pinpoint the issue.

Last time I brought my car to the dealer I had to show them how to do things, it is very likely they will never figure it out.

The car is most likely not a POS.

You need to tell us the part numbers that your boyfriend bought.
Its possible that he did buy the wrong parts.

The leading spark plugs should be RE7C-L and the trailing plugs should be RE9B-T.
Have your boyfriend look up his order and confirm that this is what he bought.

And have him give you the brand and part number for the spark plug wires.

It's possible the dealer is trying to pull a fast one on you, but it is also possible that your boyfriend screwed up. Too many hands in your cookie jar on this one.

BC.

Those part numbers are the exact ones he bought.

I cannot understand why my car has so many problems. She only has 39,000 miles on her.

That would be awesome. I will keep you updated on my car and if need be, I would definitely like to meet up with you to try to figure this out.

Then your dealer is a crook.
Go to a different dealer from now on.

BC.

I'm definitely considering that. And do our cars require premium gas? They're telling me it does. I have been putting mid grade in it, as I've done some research and read that mid grade won't have any ill effects an is fine to put in it.

If you don't feel a difference, then 89 is fine. East coast gas quality is better than elsewhere.

Ok thanks. They said both o2 sensors are fine, they took the maf out and stuck a new one in there but there was no change so they put my old one back in, they are saying now theyre going to change the two leading plugs and put different ones in to see if that helps. They took the muffler off and thought maybe that was the problem but it's not. Now they're trying the different leading plugs.

Okay, lets go back to the beginning here.

The problems you are having is that the car is stalling when you come to a stop with the a/c on, correct?

You have had the following done:

new convertor
new coils
new plugs
new wires
compression test (passed)
decarb
new motor mounts
maf swapped (and back)

Well, the next item on the list is the neutral position switch on the transmission, if its a manual, and the clutch safety switch.

Anyone else agree?

BC.

I don't see how, it wouldn't start if that switch was malfunctioning.
And the excessive heat around the floor remains, right?

Maybe the clutch pedal is badly out of adjustment and the clutch is always partially engaged? If the car is running and you clutch in, put it in gear, but don't clutch out, is there any drop in rpm or movement of the car?

Whatever the dealer tries to do, run it by people here first. Sounds like they have no clue what's going on, and if they do put wrong (god forbid regular piston engine sparkplugs) in there, you really will need a new motor. Get us the partnumbers of plugs or anything else they want to try.

We need someone local who knows rotaries to come see this car, this dealer is only creating noise.
