98 tahoe runs super rich???

[RicanGM]

if thats the case this is a good time to r&r the regulator and spider with the California spider which may give you a nice bump in mpg.

What is a California Spider? is it the conversion from CSFI To MPFI?

It's a very nice Ferrari, and in this case the CSFI to MPFI conversion.

Why don't you post the solution to your problem, and how you found it, rather than wasting space with childishness? That way, the next person that comes along with a similar problem and has the wherewithal to use the SEARCH function can gain something from your experience, and save the trouble of asking the question.

What was the cause of the problem? Someone down the line may find it helpful.

Code is p0304?

Try swapping the spark plug to a cylinder that is not showing a misfire and see if it follows to that one.

Check fuel pressure to rule out a fuel pump/regulator or leaking injector.

Have the plugs, wires, distributor or cap and rotor been replaced recently?
