Go to hondahookup.com and download the helms manuel. Its there and its free.

Thanks bro. That would be uber helpfull to have small hoosier towns don't know what honda are unfortanitly.

for future reference, we have MAP sensors, not MAF's

Ok I've got it wired up now and it runs the same i m sure I wired it up wrong the first time. Could that of killed the sensor? I've replaced the ecu with my spare same results. Should I check the spark plugs to see if they got fouled up?

Acidcrakker

care to explain what your whole issue is here

If I remember correctly you are doing a swap?

whatan00b

The swap is next month. I was just trying to fix up the half *** job the old owner did at wiring his map sensor it was just wires twisted together and electrical taped. I took the wires apart but I came to find out the wires are different colors on each end. So I in a very dumb move tried every combonation of wires to get it working. I now have it wired correctly. But it still idles like crap. I changed my plugs thought I fouled em witch they were. Changed my ecu to a spare I have same model. At it still idles really bad I checked vacuum lines and what not at the idle control screw I ajusted to no results. It hesistates in first gear till 2k and then takes off like normal and drives fine in the other gears. When I let off the clutch in nuetral it drops to 100rpmish and just bounces under a grand till you put it back in gear.

Have you checked your TPS, IACV?

These can also have the same effect on Idle.

whatan00b

Not as of yet but I will. It worked fine before I messed with those wires.

Acidcrakker

Well then there is your awnser. I worked fine before you touched it.

Dont forget to reset the ecu as well.

whatan00b

Yeah its what I figured but I didn't know if not haivng it connected would mess with other stuff.

MAF = Mass Air Flow sensor

MAP = Manifold Absolute Pressure sensor

Honda Prelude = no MAF, only MAP

whatan00b

Yes I know this now. One last question I bought a firewall mounted map on ebay but mine is a intake mani mointed one does that really matter?

Hawkze_2.3

All that matters is that you supply it with vacuum and plug in the connector.

whatan00b

killer

whatan00b

Yep that was the problem seems to be running just fine after reseting the ecu thanks for the help fellas
