Hello! I am purchasing a 96 ek hatch tomorrow. Only thing that i need to do to get the car to not run rough and turn off the check engine light is figure out how to hook up the wiring harness for the maf sensor i think. Person purchased the vehicle without an intake and immediately bought an aftermarket cai intake for the vehicle. I am wondering if anyone can point me in the right direction how to solve this easy fix. Has been a while since i have tinkered with a honda and a little rusty on them. Thanks for any advice.

 

what code is the ecu sending? there is no maf sensor, its a map sensor, and it just plugs in, you dont need to wire anything. zip tie to something if there is nowhere to install it

 

I dont have the code for it. Will probably take it to some place that has a discount on code reading. Is $40 expensive for that? The car also has a d16y8 in it. I forgot to mention that. Sorry...

 

Map sensor should be on the tb. An intake would make no difference for it. He prob means the IAT. Still tho it just plugs in.

 

Most auto parts stores will scan your cel codes for free.

 

Thank you for letting me know that an auto parts store will read the code for me!! Also is there not a sensor on the stock intake for the intake manifold? If so then it is not what i think. I owned a honda accord with the f22 in it years ago. If it helps i will post the codes if the problem is not solved. Again i really appreciate the help and will post pictures tomorrow as well.

 

you dont even have to have anyone scan the codes, you can jump the harness with a paperclip and the cel will blink to give you the code.

and yeah after I wrote that, im like the map sensor is on the throttle body, cant even be that, lol

 

Could use some help with the issues im having with this harness. When i turn the car on it idles very high and acts weird. There is very little power when i first put the car in first and go at first. Once i reach about 3500 rpm then it seems to pick up power. Not sure if the vtec is working accurately either.

 

Every honda idles pretty high at first until it warms up. Clean your IACV, FITV, adjust the the idle screw as well. You might also have to adjust your tps sensor which is also located on your throttle body. Check for vacuum leaks too. If your not going to atleast give what I put down a shot then you shouldn't have bought this hatch.

 

Half of the harness is not hooked up. I will check everything out that you said. Its very unusual that there is not much power from the car until it reaces about 3500 rpm. In every gear!! After i check all of those things out and give it about half a days lookover i will probably take it to a shop and get a professional opinion. Thank you for the advice and anything else that might help is welcomed and like i said im going to devote the most part of one of my days off school and off work checking this problem out.

 

I think I found the reason for no power until it reaches 3500 rpm. One of the head bolts has been broken. I think i may have made a mistake purchasing this car. Does anyone know what the cost for repair on this might be?

 

There's is something to be said for buying a car cheap because it has issues and getting the owner to fix issues prior to purchase. Chances are if the owner does not want to, or has NOT fixed these problems it is usually indicative of more serious problems.

If you can't do the work you might just want o call around and get estimates.

 

like how broke? head bolts are cheap, but if its like broke way at the bottom, it will be a bitch. youll have to pull the whole head and extract the old bolt out.

 

It is the head bolt near the oil cap on the motor. Idk what made me want to check that all of em were tight but when i did... That one slid right out and i saw that it is busted. Blowing air out the the head of the motor where that bolt is supposed to be. I suppose this motor would run really strong if it was not broken. Oh well. I guess that is a good reason to have some good engine parts installed. Can i get some suggestions? I would like to get the head a little beefed up since it is going to come off the motor. On a budget of about $750 to beef the head up since im going to have to pay a shop about $500 to get it tuned right and get a mechanic that has a bolt extractor kit to get it taken out.

 

Id be worried about the state of the whole motor. you have to double torque the head bolts and if you do it correctly theres no way your going to break one. Are you sure its not a valve cover bolt?

 

I tired uploading the pic check out https://picasaweb.google.com/1165392...57647168195970

I upladed the pic to there. Let me know if you can see it.

 

thats a valve cover bolt

 

those things break all the time, people think they are Hercules and beast the **** out of them, but you barely tighten those, just snug them. pick up a new one from honda, prolly gonna need to take it somewhere and have them extract it.

but having that bolt broken isnt going to effect how the car runs at all.. prolly just spray some oil up your hood thats about it, just put it back in there until you get it fixed

 

I think my stepdad has a bolt extractor kit. He is vacationing in florida with my mom right now and will be back monday. So if he can get the job done for me then that will save me a pretty penny. Will see if i can order one off ebay cheaper than the honda dealership. So this wont affect the performance of the car at all? Cause it has absolutely no power until it reaches 3500 rpm. If you want i will record driving the car and upload the video to youtube. I doubt anyone could really give me a select few problems because i dont have much for details. Would just like to save some of my money for adding performance parts.

 

You don't need a bolt extractor for those. Take off the valve cover and you'll see that all you need is a 12mm wrench or deep socket to remove the broken stud.

 

Half the harness not hooked up means half your sensors aren't doing anything. That's your problem. The engine and ECU can't communicate right and one has no idea WTF the other is doing. Fix this first.

 

Here are some pics of the harness and the connectors.

Thanks for all the help fellas!!

 

Dude that valve cover bolt is no biggie its a 10mm. I broke one recently, I couldve went to the dealership and got one but instead i went to autozone and found a similar bolt like it for 2 bucks. The bolt that I got looks nothing like original and it just screws straight down instead of having that nut on the top. I had to drill a hole through the washer so the bolt could slide in but hey it worked.
