Hey guys I have been working on my car for the past 3 weeks trying to solve my bogging/stalling problem.

My question is that I had the timing light on the car and i cant seem to get the timing right no matter how far i turn the dizzy it wont come in to where its supposed to be.

Could a faulty Dizzy cause this type of problem?

 

Btw the car is running on a obd1 conversion with a chipped p28 ecu


If I have to replace the dizzy is this the right one?

Warm up car properly to operating temperature.

Then make sure you are "jumping" the service connector that is located on the passenger side fender well and turn off all accessories devices in the car.

 

Thats the thing to even keep the car on you have to pump the gas to hold the idle so it wont stall out


everything else is off


To set the timing the service light connector has to hooked?

this is the one you use to see what codes you have correct?

 

What chipped ECU are you running?

Service connector is the one you retrieve eror codes from. It does not have to be hooked but it does have to be "jumped". Just use both ends of a paper clip and insert into the connector to jump.

 

a Neptune ecu

OK so i jump the connector like if i was gonna check for codes then set timing ?


Why does the connnector have to be jumped to set timing?

 

Ordered a new dizzy

any other ideas?

 

Who programmed this ecu for you?

Also, I would check to make sure that your cam timing is correct..

 

Jeff evans at Evans tuning .


So in order to adjust timing i have to jump the service wires like if i where going to pull codes ? After that adjust the timing to spec correct?

 

Just checked cam timing its dead on .

What would a fualty dizzy cause the car to do?

 

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

Cam timing is dead on

Ignition timing is dead on


Ideas?

 

dump bump

 

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

How do i tell if its OBD1 or obd2?

 

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 !
