smells like gas, engine burning rich

smells rich...
so far this car has burned holes in my pocket =( |
Dude.....
Get the injectors cleaned, and/or replace o-rings. Stop running the car, please. I'm not trying to be rude, so please take no offense :) |
dude...
you have a fucking unhooked vaccum line.... on a speed density ecu and you are wondering why you are running rich? |

Since there are 4 spark plugs, and I want to run a compression test, do I run the test on all 4 empty sockets or just 1 in the lead plug and 1 in the trail plug?

And btw, you can use 86-91 rx-7 spark plugs which napa or the like usually carries. Same part numbers, just no "P" on the end because they are not platinum plugs. BUR9EQ, BUR7EQ i think. |

I think you test the compression on Both rotors, doesn't matter which spot, i think...

ok update....haven't been able to do a compression test since I can't find anyone to help crank the motor while I watch the gauge.
I have taken pics of the spark plug and here is the verdict for the trailing plug on the rear rotor. Smell like strong gas http://img153.imageshack.us/img153/6153/dsc00052hp.jpg http://img214.imageshack.us/img214/7500/dsc00053ar.jpg |
any thoughts on the spark plugs?
|
Thoughts: wire Brush, and Brake / Carb Cleaner, may be able to resurrect them, but most likely they need replacing, and as far as Boost (Vacuum ) goes at idle, most normal motors draw somewhere between 4-7 inches of mercury, in/hg with great compression sometimes more.
And more than 1-5 bars of boost without the car in gear tearing down the highway, would be news to me. so far this car has burned holes in my pocket =( |

I got some ordered coming in the mail, hopefully USPS can delivery by Sat...compression test tonight!
|
your from bristow va right? you coulda made the 20 min trip to woodbridge to goto malloy mazda for them instead, i think i paid 77$ for plugs and wires!

I called Mazda and they weren't in stock, I ended getting the plugs for $28 on amazon

I have the same idle issue almost exactly the same. I have done compression on my motor and i got 110 and 107. My plugs were a nice cardboard color though. I figured mine was just because its a street port with a pettit ecu.

I did the compression test and all of them displayed 120. I will post the video below, let me know if you all see anything wrong 01. REAR LEAD test http://www.youtube.com/watch?v=WZQreiCaYvY 02. REAR TRAIL test http://www.youtube.com/watch?v=rgYD3jOdK9M 03. FRONT LEAD test http://www.youtube.com/watch?v=0NEuNiv8dU8 |
did you test with the check valve held open and look for even bounces?
|
Here is the video for the front rotor with the check valve open
http://www.youtube.com/watch?v=zE_F8wYOg-U |
The bounces look even, but does it need to hit a certain psi for succession?
|
I dont know if you have a street port or not i have a pettit medium port size and it has always bein a similar idle to yours. If you search street port idle there is a bunch of threads that say its normal for a stock or chipped ecu. Compression looks sweet though!

I'm worried about this motor since its smoking out the pipe, and after a couple of tries with the starting, doesn't to crank up, this could be the odyessy battery I'm using. Although the battery does try to turn the motor most of the time. |
can you leave the check valve in while doing the compression check? thats how you get the actual compression of the faces, you have even pulses, but they look low, when I check the pulses on mine I think I remember seeing about 30psi per pulse on the good rotor.

Your compression looks fine. You have 120 psi max pressure on box rotors and as long as the pulses are even with the valve open, that means they are all generating ~equal pressure. You need to open the valve on the rear rotor too or maybe you just didn't post the vid.
The pulse pressure can be anything and really depends on the opening, like if it is just pressed in or if the valve is completely removed allowing more air to flow out. Engine temp only has a mild effect on the compression in my experience. Not a make or break variable... may be in some cases but i don't think so here. |
