swapped full OBD1 b series, everything works except occasionally that car wont start??? i thought it was the main relay but its been replaced. main relay clicks all 3 times like it should. fuel injectors have power and the dizzy is working fine. when the car runs its pretty fast, however sometimes also i get a CEL light on. when i shut the car off and go to check the codes the light is off????? also sometimes when i drive the car the CEL goes on and then turns off. havnt had too many issues driving the car its pretty straight foward when it warms up it idel's a little high ( 1k rpms ) but other then that it runs very well. any ideas??

was it a new main relay or a used one. I find myself reflowing solder on them to repair all of the time
