First the setup

Jdm B18 Converted to OBD1 running a P28

I just turned it over for the first time and it idles like **** and when you try and give it gas it sputters and bogs i gotta pump the gas to get the revs up and when it drops to idle is stalls out.

Thanks for any help

it sounds like the timing may be off or the spark plugs wires are in the wrong order
and double check to make sure you have the map sensor pluged up

Check your vacuum ports and make sure that your MAP sensor is hooked up (happend to me).Check you timing, ignition timing and cam timing.

Sounds like you don't have the MAP sensor hooked up because when I didn't I had the same problem as you. Funny, I drove 3 miles to get to my house like that and barely made it, fixed the vac line and instant power.

Stoich

all the vacuum ports seem to be good and the motor was running in another EF and ran fine however that one was running obd0 and i converted to obd1 and swaped the dizzy

could that be it?

I had been under the hott sun all day so maybe im missing something obvious

MONSTERZC

double check your wiring and make sure you have all the grounds hooked up i see the one that from the motor to above the left headlight is not hooked up also is the ground from the body to the tranny hooked up you could try to convert it back to obo and see how it runs if you can

check your timing looks like your dizzy is a little off

MONSTERZC

that was my first guess before he even posted the pics

Stoich

Well im getting a single long flash from the CE light which is O2 sensor

But would that cause this problem?

Stoich

IAT is fine, CEL when pulling codes gives nothing but a constant light. cel lights when the car is running and stumblingh
ARGH !!!!!

make sure the MAP and TPS plugs arent swapped. This COULD throw an O2 code because if the map sensor or TPS go shitty then the ecu will go full rich to protect the motor. Try that. Also check to make sure your TPS is set to .49 volts at idle. If its stalling out at idle most likely its not getting enough gas, OR its getting way too much gas at idle. A good way to check this is pull the plugs to see if they are fouled. Also like the other guys said check your wiring. Hope it helps a lil

MONSTERZC

do you have another ecu lying around or can you borrow one from a friend. i think your ecu may be cooked.

Stoich

Well the new chipped ecu is in and the car still runs like ***

I got a timing light on there and no matter what direction i move the dizzy the timing wont come in to where is supposed to be.


Suggestions?

ARGH

to adjust timming, you gotta jump 2 wires, theres a little white plug all the way to the right. like right across from the timming belt cover. on inside of the driver side fender, under the hood.

When you try to adjust the timming, the computer adjustest its self, that jumper keeps the computer from changing. Jump it using a paperclip.

Stoich

ic is it the diagnostic jumper ?


Since i converted to obd1 the new harness came with the two wires you cross to get the codes off the ecu are these the ones you mean ?


If so i may i have found why i could not set the timing lol

No, Check your Helms Manual.

Stoich

Well the car still has a **** idle and wont rev

Cam timing is dead on

Ignition timing is dead on


Ideas?

make sure there are no bubbles in your Coolent, sometimes the bubbles will hang on to your IAC valve and **** it up, burp your rad, and try agian.

Stoich

The dizzy i got here in the Fs section has TD81 stamped on it

How do i tell if its OBD1 or obd2?

Stoich

distributor king shows this as a obd2 dizzy

When i got it on HT that **** told me it was a obd 1

this could explain my problem !
