question is does the exhaust system have anything to do with the OVP relay protection fuse. Have had problems with the fuse for about 6 months now, and last weekend i replaced the flex pipe since it was leaking and becoming really loud. Today I wanted to play with the OVP some more, so i stuck a new fuse into it and drove the car for 30 min and could not get it to pop. Does the computer monitor the exhaust fumes in some way, because a couple weeks ago i played with the ovp and it would blow after 2 or 3 seconds after the car starts to drive. NOw today after the new flex pipe i cant get it to pop. I tried to accelerate really hard, rev it really hard, brake really hard in the rain, and cant get it to pop. Now Could this be connected somehow or is this just coincidence that the relay fuse wont pop today?
