Folks,
I have an '89 Cabriolet 1.8 CIS automatic I've been fixing up. After I drive on the highway for 15 minutes or so, the engine starts sputtering. Mind you up to this point it runs strong going 70mph up hills no problem. If I pull the car off the highway, shut it down for a minute or so, I can get back in traffic only to have the sputtering (slows down to 40mph) happen again.
There is considerable buzzing coming from one of the fuel pumps. I replaced the transfer pump in the tank since it is cheap and easy. BTW, I highly recommend germanautoparts.com They are very competitively priced and I always get the parts the next day (from NY to MA) While the buzzing has subsided a little bit since replacing the transfer pump it is still considerable. Sounds like the external fuel pump (next to the right rear wheel??) may be shot or on the way out. Should I replace this next??
What do you think??
Dave
