Hello. I have a 1994 Land Cruiser that I recently bought. Close to 300k on 5he odometer and has been running fine until last week. Started to idle rough and accelerate poorly. Been going through the different threads to pinpoint the issue. What really has me stumped is while changing the spark plugs, i noticed a connector to the driver side of the back plug (under the egr modulator I believe) was unplugged and looped back into its self on the female side. Also the EGR modulator tubes connecting to the throttle body were disconnected and looped back as well. Both sides. The throttle body side and modulator side. Is there any particular reason for this? Could it be my problem for the idle and acceleration? Don't want to plug them back in and cause a bigger problem. I'll try to get pictures after work.
Thanks.
Thanks.
