i'm trying to decipher that run-on sentence.

108 octane?

when you put the p28 in the car, it throws codes? well.... what codes are you reading?

4500rpm is usually limp-mode and could be a number of reasons why. most common is due to spark/distributor.

when you say, "i just converted my car to obd 1 and now im having drama" does that mean your car has ran terrible since the obd-0 to obd-1 swap. or it only started acting up when you put the 108 octane in the car?

 

I'm going back out there and check again. Sorry for the run on i couldn't help it i just ran inside really quick.

 

car was pinging thats why i used the gas didnt think it would after me that much its 2 long pauses i remember that much and ima go check the others right now

 

your car shouldnt ping with the build you described. adding 108 octane isnt going to fix a problem either.

my guess would be spark/dizzy related, weak spark or bad rotor.

 

4 long pause and 1 fast one , and 2 long pause

 

motor is fine it only has 130 miles on it was running fine obd 0 maybe plugs wires or dizzy possible

41 Primary oxygen sensor heater - probably cause for the pinging.
20 Electrical load detector - cause for the 4500 limp mode + pinging.

you did switch to a 4 wire o2 sensor when doing the obd-1 conversion, right?

 

o u said rotor hahah my fault

 

Yup I changed it but i used the rywire harness, and the wires they wanted ran didn't match up so maybe its mixed up or something. How would i go about fixing the code 20 problem

 

so, instead of checking the normal maintenance items like cap/rotor, ignitor, plugs, plug wires you poured in 108? hehehe

replace the gas and the above mentioned parts and you'll probably be golden.

but i have a feeling your distributor wiring isnt up to the task of running properly for obd-1.


code20 is either bad distributor or bad distributor wiring.

 

i have the rywire adaptor harness i didnt touch the wiring

 

Car was making the noise since it was obd 0. So i didn't think dizzy cuz i know i didn't have 2 bad ones thats why. I tried the 108 it was worth a shot but all i know is it was running fine with 91 and now its not lol.

 

beats me.... contact rywire to see if they can shed some light on what you did wrong.

 

where in the hell did you get 108? aviation fuel is only 104
