my car isreally **** up..... its smells like its running rich.... it idles horribly and after a min or so of idling it will start to die unless u give it gas... i put on a new mass air meter... its the same meter just transfered it over to a big housing... and hten an inlet pipe to as well and a throttle body and lt headers and prochamber, new spark plugs and spark plug wires, and new rotor and distributor cap... and i will put the new underdrive pulleys on when i can get it out to the shop were the air wrench is... i would take it to auto zone to get the codes read but im afraid ill only make it half way or sumthan it will just crap out on me... anyone have any ideas??? mayb it needs a tune...

does anyone have any advice on were to start... i havent drove hte thing for 3 weeks and its killing me... were should i start to look for the problem??.... ive looked to make sure all the bolts and everything are tighted down... but i really dunno what else to do

 

Did you try to reinstall any of the old parts to make sure you don't have any defective parts, just a thought. I am not trying to dumb you down.

 

set your idle screw ion some more and get it ideling. then take off the connector on the IAC(side of the throttle body), and loosen the idle screw until the idle comes down to what you want it to be. then set your tps voltage. try this first and then get back to us. Oh, also, take your IAC off the car and clean it with brakecleaner. that'll help also

 

i have already cleaned all of the parts and most of the old parts are in pieces which is why i replaced them.... i place with hte idle screw and sum other screw on hte tb and got it running pretty good... its still not good enough but i can drive it agian... thanks for the help... im htinking i need a dyno tune... im curious what my numbers are anywayz.. and i think a guy in my mustang club owns a performance shop with a dyno so ill need to talk to him... cuz it still smells a lil rich.... but thats the help i been driving it and its lots of fun... i am wondering whats up with this now tho... when i take it up to high rmps like 5k or so its kinda stalls a millasecond and then jacks up to like 6k so im nto sure about that... i wasnt runnign it to hard i was just runnign it throw all hte rpms to see how it was doin... and i noticed that... im a lil worried about it but it didnt do it every time... only did it twice outta 5 times... any ideas on that???

thanks for the advice so far... im goin out tonite ill check bak with the post later tonite the all of tomorrow is dedicated to the good old cobra make it shine and try and make it idle a lil smoother

 

Is your mass air meter calibrated to your injectors?

 

its the stock meter but onto a differenet holder... so i would think so... i mean.. unless the step up in airflow is throwing things off

 

So you transfered the electronics to a new housing? Is that correct? If so, what meter did you go to?

 

if its a c@l the housing is calibrated

 

yea its a c&l meter and inlet to 76mm and the tb is a 75mm bbk

 

i tried to go to autozone and get codes read but after lookin at it he said he couldnt plug into it

but yea hte mass air meter is just same electronics on a c&l housing

so what do u guys think??
