Re: Help
Rotten egg smell is a righ exhaust. (Code 13 usually) The TBI unit itself may be the issue. On top of the unit is the fuel pressure regulator which is known to fail but they usually fail lean. The temp sensor may also be telling the computer the eng is ice cold which richens the mixture. I think thats a code 14 or 15. Then there is the MAP sensor which works in conjunction with the TPS. MAP sensor reads manifold vacuum and the TPS reads throttle position. The MAP failure code is 33. I don't remember the TPS code. Also another thing to look out for is the TBI base gasket, which is the place I would go first. Check that with some carb spray, eng running. jim
