Hissing!?! Posted by RS [Email] ![]() ![]() ![]() In Reply to: 1990 16i running again - FPR question???, PJ Cats, Sun, 14 Dec 2003 02:40:18 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I've never hear an FPR hiss, but I'll go out and have a listen when I head out this afternoon.
The relay might be bad or the output transistor on the ECU might be bad. Which market is your car from? US? GBR?
My guess is that, if you can hear it hiss over all of the other engine bay noises, even at idle, the seats might have some erosion and are sloppy enough to do a poor job of regulating the pressure to the fuel rail or you might have a very small breach in the diaphragm.
Do the plugs look like it's been running excessively rich?
