1987 VW Cabrillet 1.8L - no power
75

Asked by mstjohn1974 Sep 06, 2010 at 08:17 PM about the 1987 Volkswagen Cabriolet

Question type: Maintenance & Repair

I have a 1987 VW Cabriolet 1.8L since a few days I am having some trouble with my VW. The car idles very low at 400-500 rpm and has now power while driving. I replaced the following parts so far.
- Fuse Box (some sockets melted away and replaced them all with new fuses) also some rewiring was necessary
- Fuel Pump Relay + Fuse
- Fuel Filter
- Ignition Coil
- Ignition Wires (the entire set)
- Distributor Cap & Rotor
- Spark Plugs
- Air Filter
- I checked all vacuum Hoses with Flammable Brake Cleaner and the ones that leaked I replaced

I can't measure the fuel pressure because i don't have any Fuel Pressure Gauges. I suspect that the fuel pump is not okay but would like to be certain. Any Ideas what else could be bad?

Also I have three parts I cannot identify any idea what they might be.
