Just put a B20 in my 90 teg. I ran it on the pr4 for a lil bit until my obd-1 dizzy arrived. It didnt throw any codes. Well i put my dizzy on and the p75 wit the jumper to convert to obd-1. Now all of a sudden my car throws code 9 and 20. So now sometimes i will have to pull over because my car will start stuttering and wont run rite cuz it starts to sound like im runnin off 3 cylinders. Ill let it sit for about 5 mins and then drive off fine. I know code 9 is the cyp sensor in the dizzy and it detects where the number 1 cylinder it at, but the code 20(electrical load detector) is what is bothering me... it never threw these wit my pr4.

Any advice would be great

thanks
