Good question could be a case of old hondaitous lol if its doing what he said burp the cooling system really good, also if the tach is going crazy check your dash grounds mine did this after my k swap, was just a loose ground hope this helps :thumb:

#325538 Brandonthesmith no when the car is at full stop it rev all the way to 7rpm but when i take of in 1 when the rpm hit 4 my car sound like it breaking up the only thing i did was convert the distribution form obd1 to obd2 that's it

#325543 Oh, its very important to explain what is going in detail as well as what you did before it was acting up.

What kind of wire conversion was the engine originally obd2? Did you purchase a ecu plugc conversion and go from obd1 to obd2?

Did you swap an obd2 dizzy and convert it to obd1???

These things are important to help further diagnose :thumb:

#325584 My wire harness is obd1 complete bout i had to transfer evrything from the obd1 distributor to the obd2 distributor so the obd2 distributor bolt up to the 16y7 i paid 25 to do it because where i went they didnt had the obd2 to obd1 conversion harness. An the thing is am not getting any cel :cry:

#325587 sounds like a crap job, did they solder it together or use butt connectors? and the other thing is make sure you have a cel

turn the key on, does the cel illuminate? if so your good

the other thing to check out is your spark plugs, timing, rotor, cap, and again inspect those wires to the distributor

let me do some research on your distributor and engine ill get back to you soon if you don't figure it out by then :thumb:

That info helps :thumb:

Your car & engine harness are both OBD1, why bother with an OBD2 distributor & converting it to OBD1 when you could just use an OBD1 distributor? Unless I'm missing something here...

D15b7 and D15b8 Distributor bolts right up to D16y7 and D16y8 heads, plugs right into OBD1 harness. Also remember that an OBD1 distributor has the crank position sensor inside the dizzy while OBD2 motors have them located on the other side of the block, by the crank.
Put on a D15b7 dizzy and call it a day :thumb:

#325596 teal_dx you are right about the crank sensor, if you dont have crank sensor voltage your car will run like garbge or not run at all. ive seen some wierdness surrounding the crank sensors....

go back to obd1 save the headache
