Ok guys heres what happened I was at our autoshop on post changing my oil and sparkplugs(and wires). We changed the oil with no problems. Then we went and changed the spark plugs...heres where it gets ugly. I was lookin at my ail filter deciding if it was ok or not, while my buddy was changin the plugs. Well little did i know that advanced auto instead of giving me leading and trailing just gave me trailing. Well he doesnt know any better so he just installs them..so when we go to start the car it runs like crap. So we fix that problem and then install the new wires....and once again he screws the wires up. I finally break down and go to mazda and find the wiring diagram and get them right. But the car still runs like crap and shoots smoke and keeps missing. At this point Im ready to just destroy the car. My only Idea is that maybe the timing is off. Also I have never blown a apex seal but maybe thats what happened. Just lookin for some help im totally out of ideas.

 

well to me sounds like ur coils might be bad! take ur coils out and messure it in ohms make sure there in specs!......also double check the gap on the plus make sure there perfect to specs as well..............good luck!

 

I'm guessing your engine might be flooded.

Also be certain your MAP sensor is plugged in.

 

Well what kind of plugs did you put in the car? did you take the intake off to change the wires out completly?

I would say your timing has not changed and you just have somthing installed incorectly. The coils are labeld with leading and trailing and which rotor. You could always try installing the old plugs to see if anything changes.

 

The more I think about it, the more I'm convinced you need to start at the MAP sensor.

 

There is nothing wrong with running trailing plugs all around, most of us with modified cars do that very thing.

Next time only replace one wire at a time (good advice for any car).

Make sure the wires are properly connected, the UIM was put back correctly, and that your MAP sensor is still connected.

Boy, if you are already ready to destroy the car just from this little thing, maybe you should reconsider car choices.

destroy! destroy!

 

If you took off the intake elbow in order to give you more room for the plugs it is not uncommon to unplug the vacuum line that goes to your map/boost sensor by accident when reinstalling the elbow. I'd check there first.

 

Simple mechanics....gone wrong...!

In the future I recommend taking the car to a professional rotary shop. Seriously.

If you're ready to destroy the car with something as simply as a spark plug change, I see a v6 Mustang in your future

 

 

If you got the plugs from Advanced Auto, most likely they sold you Bosch plugs. These plugs are no good for a Jap car. If this is the case, go get some NGK's from the dealer. If I'm wrong, go with the suggestions above.

 

Lol I wasnt bein searious guys about destroying the car...took me too long and was to hard to get it. The sparks plugs ark NGK they were the same that were in the car when I got it. I did take the elbow off when I installed them. Im guessing you are talking about the vacuum like that bolts on the elbow. I checked that and its good as well. Umm Now for the map sensor where exactly is that located?? Also Im deeply hurt emotionally about the mustang comment...they are a plague to humanity. Also could anyone hook me up with anothe wiring chart by any chance?? If its flooded then, I should just beable to leave it set while im at work and it should start when I get back right? Thx guys for the help...I know Im just trying to learn as much as I can about my car.

 

The map is right behind the hose that comes out of the elbow. It's above/behind the oil filter, mounted to the firewall.

 

Yeah, next to the brake booster

 

The big vacuum line on the elbow is usually what knocks off the small vaccum line on the MAP sensor. The sensor is on the drivers side firewall at the top and says Mazda Boost sensor if I remember correctly. There should be a thin vacuum line going to th ebottom side of the sensor. If you only see a nipple and no line then it cam off. Find it and plug it back in. Hope thats what it is.

Mazda dealers are not much help on the FD's. I wouldn't even waste my time talking to any of them anymore. Only exception to the rule is Malloy Mazda where Ray Crowe is.. "Ray Crowe is da man...."

 

....So that would cause it to act like its misfiring and run rough as hell

 

There are no Bosch plugs available for any year RX-7. There are only Autolite (not reccomended) and NGK plugs listed for RX7s in our computers. Also, all of the Advance Auto stores stock BUR7EQ and BUR9EQ NGKs as they are the stock plugs and fit all the 13B engines.

Yes.

If ever you find us talking about something that you're not familiar with, consult the FAQ thread (it's stickied at the top of this forum) or run a search for the term.

Ok will do I was lookin through there for about a day and half before I decided to post but I might missed somthing sorry

 

what the hell does that line go to off of the elbo anaway i pluged mine

 

Accelerated Warmup System. It revs the car to 3000 rpm when you start it cold to help it warm up more quickly, I recommend every FD owner delete it.

 

That is the most gentleman response that I have seen in awhile on the forum you are a lucky man, must be that Colorado water.

To test your coils you first touch your leads toghether and take that measure (which should be in Ohms) and reduce it from your total. This should not exceed 1 Ohm. In other words, lets say you touch your leads get 0.4 ohm but then test with your coil and get 1.2 ohm that means the coil is at 0.8ohm (all imaginary numbers).

For your MAP sensor it is a little black box with is screwed into the firewall with a 10mm. On the left of the brake booster it has a vacuum nipple facing directly downward( as in towards the ground). If it is unplugged your car should run pretty shitty.
