THE STORY:okay i did my motor swap back in 07 it ran pretty good but i blew the water pump right after, and didn't get a chance to put the new one it to get it back on the road. so it sat in the garage for a yr.
the next summer, when i should have put the water pump in, I didn't, i got a 4x4 and started off roading and just kinda left the mx3 in storage
well this yr i found out that they are now selling projectors on ebay ... it motivated me to put my jeep down and star playing with the Mazda again.
THE PROBLEM:so i start it up and it runs pretty decent but when i step on the throttle the rpms dip kinda hard and then spike right to where they should be but it kinda sounds like its studdering i know it has bad gas in it but im more concerned with why 5 out of 6 of my stainless header pipes ended up turning blueish from the heat ... but one did not. is that cylinder not firing? if not what could be causing it and how do i fix it ...
any ideas would be helpful i need to pull the motor our this weekend get the new water pump in and put my mazdaspeed motor mounts i have had sitting around for two yrs in while its out i would love to take care of what ever this issue is i can get a vid of what it sounds like and it running tom to show you guys what it sounds like maybe that will help you diagnosis it for me ... any ideas or tips would help a ton ... oh and its not pulling any codes

suspect indeed...did you check the plug on the cylinder in question??? if you dont have the tools, a simple old skool way is to disconnect the fuel pump, remove the spark plug in question, keep plug wire attached to it, and have someone crank the engine over while holding the plug near a ground source(chasis)...just make sure you use common sense and dont fry your self by touching the body of vehicle while doin this(did this with my first car and got quite a shock when i was a teenager, back in the not so good ol days of street racing and runnin from cops)
anyway, if you see blue spark, then it's not your plugs/wires/disti...

K8DE, see web site...too many mods to list, but still growing.
2006 Dodge Durango (The Family-Mobile) Every time you race a Honda Civic, a kitten kills a retard.
okay so no video because we hooked it up to a charger and it runs pretty good with the charger on the battery so i would assume the alt is bad ... would that be causing my poor running up to this point? the cylinder i was concerned about is getting spark but seems to be a little short on fuel i have spare fuel rails so ill just swap and see if that fixes it
i wanted to know however if you guys think this alt is a good buy vs the 200 for one at advance or else where im trying to put ksport coilovers on so money is tight as hell
i would love some input by tomorrow at the latest as im going to need to put it in this upcoming week
thanks guys for the help thus far sorry for being so noobish but i have been out of the mx3 game for 2 yrs and its slowly coming back

okay i figured out that one is the wrong one it would work but needs a mod i dont have time to find a millennia alt plug so im just gonna get one from a pgt.
swapped the fuel rail and the motor is running mint now. how ever idle is kinda goofy some times half the time it idles fine half the time it kinda revs up and then drops right down it "pulsates" if you will just wondering if any one had any info on possible problems for that.
