1985 740 GLE manual trans m-46 od
i have signigcant loss of power and chugging underload and idle is around 1000 rpm.
I have read about fuel smell on vacuum side of FPR and am wondering if the thin hose towards the front of the car at the fuel rail is the vacumm side.
When I take off the thin hose on the FPR ...idle surges. Is that good?
Also what troubleshooting meathods would you recommend? I checked to make sure all ignition wires were on tight and will pull the plugs and have a look see.
I pulled off the AMM connection ( ingnition off) and started car. it still idled although not well.
I took off the hose from IAC valve towards the air intake and car died. Is that good?
I've screwed in and out the mixture screw Black round plastic thing and didn't notice to much of a difference.
Please help
