WET WEATHER POOR PERFORMANCE

1987 Volvo 740

Engine Performance problem
1987 Volvo 740 4 cyl Two Wheel Drive Automatic

Hello
In wet or humid weather my 740 gle has little or no acceleration. I have already changed the plugs, wires, dist cap and rotor but it is still the same.

What can the problem be? It's fine when its dry outside.

Hi volvoquestion001,

I would suspect the TPS or crank angle sensor to be the cause.
