Help & ? for guy's who don't drive they car in the winter but
 

Hey I have not driven my car since it's been snowing up in the NE on regualry basis {like over 4 months}, anyway last week I start it up it rev fine and then the idler comes down but the car start to shake and backfire alot. Today I deceide to start it again it fire up fine, but again when the idle comes down the car start to shake and backfire and now I notice the idle is hunting and getting very low like the car will shut off by itself? Also I notice that when I rev the car it sound like only 1 rotor working? Can the car start up fine but still has 1 rotor not working properly? Also my exhasut is completly is aftermarket so I no it's not my exhasut, and I had removed my 2ndary butterfly but leave the asw connected cause & everything else but I alway start the car in 1st gear which delete the asw. I have no cluse what is going, anyone ever exprience this stuff b-4? any input will help damn I never thought I would be on the other side? thanks, khris

Did you put in new gas or are you using that 4month old fuel?

4 month old gas will work just fine.

Check the MAP sensor hose. MAP sensor is a little black box near the throttle body. If it is disconnected it will cause symptoms you describe.

i have no idea what happened to my car after sitting either. i had the same problems as you today. it was actualy nice out and i wanted to go beat the shit out of it... no such luck. there is a huge miss, none of the guages work and it is running lean as all hell. (reading 19.8 at 2k rpm on the fjo) :rolleyes: and back fire like a madman!!! huge flames after the throtle closes.
i will try to diagnose it tomorrow and see what i come up with. i didnt realy look for the problem just got pissed off and let it sit and then went drinking. :D
the one thing i did try was to zero my timing in the haltech. i recently did it for 2 other FD's i put a e6k in, and never did it to my own.... could not get a fucking signal and timing light worked fine on another car today.. :confused:

oh, and my map sensor is fine.

*edit*

i left my FD in the garage for a month without touching it. did the same thing. they don't like the cold. just rev it a little to clean up the plugs and let it warm up. should be fine. this is completely normal. all my cars did this when i let sit for long periods of time. khris you don't need a new engine. let me borrow it. i can clean out the carbon for you :D

Hmmm, my car sits every winter. I usually start it once a month, but sometimes I don't get around to it (or forget) so it has sat for longer periods. It's never done anything like that.

jon, side question for you a fellow haltech user. do you ever get a backfire just by putting key in on position? i do and it starting to worry me as a friends backfired in the intake and blew the gasket between the TB and the plenum. :eek: just wondering if your ignightors are firing before car was on. or if yours is similar. maybe you can ask Ito if this is normal? :confused:

Well I start it up today and it run fine, However I was correct my back rotor got stuck for couple of seconds which cause the car to run crazy like if the devil was in it. Yeah Jon, I think should give u my keys so the car can get a person who can drive it like it should instead of it just sitting in my garage. btw do u have Jay email address? I need my mazdaspeed hood to be painted, khris

Hmmm, mine has been sitting too, and I've recently done a vac. hose job and will be putting on my intake/downpipe- I wonder how mine will act...

my problem was very fouled plugs. :( runs fine now.

mine never did that putting the key into the on position. that is not normal..... i'll ask him about it next time i talk to him. maybe you wired the ignitors to a constant power instead of switched power ?

sounds good! jay's email is jaytech@optonline.net he is in mexico right now so you won't get a response for a week

wouldnt turning the key in the ON position and then it happening BE a switched power? that does not make any sence to me... :confused: see if you can ask him for me. :D thanks. :bigthumb:
