So I have a 98 dx hatch... had a y7 and i found myself a y8
ive done the swap 2 weeks ago and have been working thru the wiring.
( using my stock harness )

Ive found a couple write ups saying how to run the vtec wires ( 2 and a ground ) to the ecu,
also needed to wire the KS to the ecu. very simple.
double checked triple checked my wiring. even with the haynes manual.

So heres the deal.. cEL is on.
ran a code checker... came up with p1259 ( vtec system malfuntion )
and p0108 ( MAP high circuit )
I have a P2P ecu
stock y7 dizzy

The car starts up and runs at idle. but when pushing light on the throttle it bogs and dies
Ive been playing with this for almost a week now cannot find anything on this. or what the deal is.
As far as the vtec goes.... ive read maybe change the oil. did that today.... still throws code.
also read that it might be the oil pressure switch on the vtec

I also swapped out the map sensor for the one that came off the y7 ( never had any probs)
So if anyone has any help or any ideas... please let me know... the bigblock chevy is starting to kill me on gas and would love to drive my hatch again.
PICS WOULD BE MOST PERFERD....
thanks in advance HT

BUMMPP ANYONE please help....
came up with a semi plan but cannot find the scamatic....
im just going to wire the map sensor straight to the ecu... but i need to know which 3 colors go to what on the p2p ecu for the map
thanks
pics would be great.... but not necciary, 3 wires on map to 3 different pins on ecu.. A,C or D

Well your vtec isn't going to work unless you wire it up unless you have that done already. And someone correct me if I'm wrong but I thought you would have to use the y8 dizzy, not y7.

The y7 dizzy is the same P/N as the y8, so your good there. Make sure you have the vtec wires going to the right pins at the ecu.

1. I'm assuming you did the IACV wiring fix.
2. You need to wire in vtec for it to work. It's not magical lol
3. Change you map sensor, if that doesnt work you have a loose pin or frayed wire somewhere.

Are you sure you didn't swap around the plugs for MAP and TPS, also as stated above I'm assuming you did the 3 to 2 wire IACV?
