car not running right after removing this wierd little box

[goj_cloud]

i have a 91 240sx stock ka24de, i open the hood because i notice when the car heats up the temp only stay at 3 notches instead of the needle being half way. i notice this box that was wired up to the maf, and i was thinking "this shouldn't be here. i pull the little box out and rewire the maf to the way it was, i started the car it idled really ruff if, i hit the gas and let off it will die.

its really rich also i have to stay on the gas in order for the car to stay on it jerks too. what is this little box for, ive had 240's b4 and ive nvr seen this before. i know it was working before though, but i checked with a mechanic to see what it was. he said it was probably a bypassor or somthing like that cuz the maf or the ecu probably didnt work. i also kinda messed up the wiring while taking the box out.

my question is, do you this i need a new maf and its wiring harness or is it something else heres some pics.

looks like the guy who had the car before you f***ered up your MAF plug.

cant tell ya what the little box it. looks like it was rigged on there .

If you fix the plug wires properly that will most likely fix your problem from what you have described.

oh okay so were could i order a maf harness at?

[Rev_D21]

Best bet would be to go to a junk yard and hack off it off a junk car. Get as much wire as possible with it.

Try a junk yard or mabey ebay. Some people remove the stock maf plugs when they up grade to a turbo set up.

[goj_cloud]

so is it a bypassor to bypass the maf?

[jdm_dean]

yeah you need a new maf connector. damn the two wires werent even protected from each other? definately could cause a short

[goj_cloud]

this is the maf i ordered http://cgi.ebay.com/ebaymotors...%3AIT

if i install this and its still running messed up what else could the problem be?

Looks like one of them " 50+hp and 100+mpg" BS things they sell on ebay.

[goj_cloud]

thats what i was thinking the mechanic also said it could have blew out my ecu could this be true?

[P_856]

its possible it could of shorted the ecu

[goj_cloud]

so i should also order a ecu also if the new maf doesnt fix it? dang if i get another ecu then that should be it all right, there could be no other possible damage to any thing else right?thanks guys for being patient

[goj_cloud]

while it was on the emissions was kinda high

[goj_cloud]

dont mean to be rude but this doesnt have naything to do with my problem. this problem could only have damaged the maf and the ecu right?

Don't order anything until you are sure it's broken. A junkyard will be much cheaper than most prices you'l find online.

chris has great advice....but let me add to it...

pull an intire harness from the junk yard and grab the ecu wile your there..ecu will run ya 30 from a yard..and harness around 40ish....with the hack job on your current harness..it might be benificial to just replace all the hacked up connections your not see'ing...better to have a fresh start..allso..grabing the ecu with that harness will inshure that the ecu is compatable forshure..insted of the ebay risk of not knowing exactly..good luck man..hope this helps.

this is what im currently bidding on http://cgi.ebay.com/ebaymotors...06919

i just ordered this http://cgi.ebay.com/ebaymotors...NX:IT

[liquid_cool]

yup ...you need both of those..hope ya get em cheep!...btw..the ebay posters..just junk yard dive for em..and then post em..lol..some yards sell on ebay allso.

[goj_cloud]

is there any chance that it could have shorted out anything else?

[goj_cloud]

my ecu is #30 what other number ecu can i use

jim wolf has a ecu list that we ka guys can cross refrence...i believe its stickied somewhere on the forums....i know from experience..if your running an 5speed..you can use both auto and manual ecu's..in reallity..an auto ecu is preferd..as it does not have a 4th and 5th gear limiter on it..unlocking the cars potential..but cat what ya can find for now..and reasrch a little more..good luck

[goj_cloud]

thanks for the info everyone i ordered both parts my maf is here but i think it might be safer to install both the ecu and maf together.

ill let you guys know what happens

[goj_cloud]

hey guys my problem was fixed after putting in that new computer and maf. the only thing is it mis fires a little when im idling what could cause this?

[Chris28]

Try changing your plugs. They might be fouled after running rich.

[goj_cloud]

yea i was thinking that thanks
