Default I call her Casper

Hey everyone. I just recently bought a 99 white miata. I recently got rid of my 2010 speed3 because I was afraid of blowing my motor and not having the funds to get a DD and fix the car while making the car payment. Well I wanted a miata for a bit before I got rid of the speed. So about a month after I got rid of the car I found Casper on ebay and it was local and supercharged. I was estatic about it and went and saw the car. It only took once and I picked it up for 3500. There were a few problems with it but I thought it was simple. Turns out not so simple. The last 2 months I have been struggling to get the car running right and finally got fed up and took off the supercharger. I planned on turboing it anyways so that just makes it better.

Here are some pictures of the ride:




Current mods:
Raceland Coilovers
Harddog Rollbar
Jackson Racing Headers
AEM Boost guage
Brainstorm exhaust

Had:
Jackson Racing M45 supercharger
Trackdog Intercooler

I also picked up a few goodies from soviet the other day. Was great to meet him.

Plans:
Begi Cast manifold (soviet)
Begi DP (soviet)
550cc injectors (soviet)
T25 SR20 Turbo (573)
DIYPNP
Ebay bride seats
and a few other goodies

I have been having problems with it. If anyone has any insight then I would much appericiate it. Here is a short youtube video showing my problem. For now I have a homemade intake.


I was thinking it is misfiring but not sure. I replaced the spark plugs, the ISCV, and a few other parts. I am starting to read a bit about the TPS causing some problems in the car. I have had some bucking doing down the highway and things a bit. Anything would help me.

I'm pretty sure I can hear a vacuum leak, but by taking the video in the garage, you introduce a crap-ton of echo and exhaust noise that negates using sound as a diagnostic tool.
Back it onto the driveway and re-record.

Also, only **** name their cars. There are exceptions to track cars and vehicles that have an extensive history in either awesomeness or blood. Yours does not qualify. This is irrelevant if you're actually gay.

Oh yeah... Casper The Friendly Ghost was a raging queer.
Welcome to the forum.







PS: I'm only giving you shiz because I'm super-jealous... a lightly modified white '99 is what I dream of at night when Casper isn't haunting me.

Yeah I have thought about a vaccum leak but I am not sure. I believe what you are hearing is the fan that is turned on. And Lightly modified is an understatement. And this has been a big headache so far.

I dont care about internet ----. And I didnt actually name it that is what the last owner called it and I just liked it a lot so I kept it going.

I will back it out and rerecord but it doesnt always do it everytime I turn the car on. Thanks for the input.

Build thread? I don't need no stinking build thread!!!
Actually I have a spare motor waiting for me to work on to swap in my car, when I start stuff on that, I might make a build thread.
PM me for questions about my current setup.

99/00 coils are known to fail. Have they been recently replaced?

Yep, car looks pretty good in person.

I think your biggest problem with idle is the Powercard. Kill it with fire. Get MS3+MS3X. Live happy ever after.

Soviet it shouldnt be having any effect anymore because it only comes into play when there is boost. But I am going to disconnect it here in a day or two. I am also gonna change out my TPS with one that a friend has to see if that solves anything as well.

I did a compression test today and it was just fine.

#1 170, 170
#2 165, 170
#3 160, 160
#4 180, 175

I am also trying to get a TPS from a friend of mine that said he had one laying around. I am also hoping soon to get a DIYPNP. I think that part of the problem is with the ECU. The powercard is still spliced in and it needs to come out. Next thing on the adgenda is to build a boost leak tester and see if I can find some vaccumm leaks.

Not a big update but when I got the car it had a broken antenna and the stock Bose CD player didnt work so I had no music since I had the car so I put in this old radio I had laying around the garage.

Also got an ultraguage today as well. I am gonna mount it like this.

The ultraguage got a CEL of P0123 which is a TPS high voltage. So I am going to be checking the sensor and checking all of the wiring to see what I can find. Hopefully it is a wire I can just patch up and get back on the road.
