2001 B3000 Mazda truck vibrating when idling and accelerating but not when accelerator is released. Rotten egg smell when problem began, but seemed to fade when heater turned off. No smoke or odor under...


have you had the catalytic converter checked at the local exhaust shop? try that first. is the truck a 4wd? time to start checking the ujoints. do a compression check on all cylinders and see if there is a major drop in that hole that is misfiring. let me know what you come up with.

Flasher Relay location- 1998 Mazda B3000 pickup 4x4


it's basically a stand alone relay... most times... look for a relay by itself and often round. my ford winstars flasher relay was actually located in the fuse box under the drivers side dash. it was blue and larger then the other relays so that may be a clue to you.
