ok so i have 3 cars as it is and im stupid to buy another but it was a deal i would never pass up

its a 93 coupe with a d15b8,ive noticed hf intake manifold(small ass throttle body)

well here it is,the car will start,instantly idle high as hell then will shut off.if i give it gas wo keep it on,the intake will shoot air out and make cracking noises,also there is a plug just hanging out and im not sure of what it goes to,one goes to the map sensor,one goes to the throttle body sensor?and the other im not sure of

any ideas will be greatly appreciated

Do you have any codes?

Yes, how do I pull them from an obd-1 car?

well u can research how on honda-tech....or u can go to autozone and have them tell you.

well now it will start and idle but it surges

like im guessing from 700-1500 and the brakes are firm(no vacum to the brake booster?

im sort of going through the same thing. 1st off you need to know what codes you are throwing.

once you know what codes youre throwing, youll probably find out what sensors that are bad thats making your idle go up and down and replace them. on my new car i just bought, it was my ECT water temp sensor, the vtec pressure plug was plugged into there. and if the ect is missing the computer will blog up and down and have a hard start up. good luck

also do you have an aftermarket intake filter? a common problem is youre fitv/iacv might be dirty. making the idle rough.
