I inspected the fuel pump relay yesterday. I was surprised to see that the cover had been "sealed" with some solvent and thus would require a bit to remove and thus reveal the circuit board. I saw a build date of "2000" and this relay was mfg in Hungary. Obviously this relay is not original. The A/C relay looked original (by comparision) with a build date of 1986 and a Bosch trademark. I did not try to take apart. I think I should replace the rotor and cap. Move on from there to coil and wires. The car is running fabulously with a a "shudder/miss" that last 2-3 seconds on 3 occassions over the last 125 miles. What do you think? Prudent? Or should I continue to suspect the relay? Thanks!
