Hey!

Got a problem with my Cobra, it seems it wants to miss/stumble in fifth and sometimes fourth gear. Also, most always it happens when it is going up a hill.

I plan to tune it up this week with NGK's and MSD wires and new fuel filter. My first tune up with this vehicle

Could it be fuel pump related? imrc's dirty? It runs great except for the miss in Fifth, i get the nice burst of power smmothly after 3250 rpms. So I know the IMRC's are opening smooth.

car has 80,000 miles, no mods except for K and N and Flowmasters. Still searching for someone reputable for my 4:30 gear upgrade, cant wait for that!

sorry if i am asking a repeated question but could not find my problem with the search engine

take it easy
J.
