Hi, everybody, I have a 1998 honda accord lx. It was working fine till yesterday it started idling really funny. Instead of idling at 750 rpms,its idling at 1200 or 1300 rpms, then the motors surging. i cleaned out the intake system there, and it doesnt help. does this sound like the map sensor?will puttin iton the computer tell me exactly wat it is? sorry i didnt have the car too long, and am just learning. thanks for all the input.

 

Moved your post to correct forum for better response.

If Check Engine Light is on, go to Autozone, get the code read, and post the code number Pnnnn.

good luck

 

Hey thanks a lot for replying. i got myride checked out today. it shows the numbers, p0108, and p1519. so if any body has any advice, id appreciate it. shud i change the map sensor?? another thing, my power windows on the passengers side sometimes dont want work, then the next time they work again. also the power lock doesnt work at the same time. i checked all the fuses, and the wires and cant find anything. and advice, thanks

 

What does shud mean?

 

First reset the ECU w/ OBD2 scanner and see what codes return. If same codes, heres meaning.

P0108 is Manifold Air Presssure (MAP) circuit High input. This could mean failed sensor, damaged sensor connector, damaged wiring, or possibly faulty ECU.

P1519 is Idle Air Control Valve (IACV) electrical fault. Similarly could be faulty IACV solenoid, IACV connector, wiring, or ECU.

You need a shop manual to check. Check Autozone for an online manual to get the specific diagnostic steps to perform to isolate source of faults.

good luck

 

hey thanks a lot for replying, another thing, is it worth putting on a cold air intake? improve gas mileage? i think id be worth putting it on just for the sound and look? wat r ur thoughts?

 

I think they are a worthless waste of time/money, but they do change the sound of the air intake.

good luck

 

Hey sorry guys i might be kinda stupid, but.... i still have the idle problem, it idles now from 1000 to 2000 rpms. i took the air intake manifold off, cleaned it really good, and it still does. i reset ecu, now the only code that comes up is the iacv code. so this means its for sure the valve or not? shud i change it?? please help, desperate

 

Depends, what does shud mean?
