'94 318i Fluctuating Idle At Start Up Power Loss
Would appreciate anyhelp on this one anyone can give me,
Here's some background on the issue.
Brought the car 2 months ago and it has always had the idling issue since the begining. Cold starting the idle is steady and when driving cold i don't notice any lose of power, but when hot starting most times the idle will fluctuate between 1300 - 200rpm (sometimes stall) only during first 20 seconds of running and i notice on occasions when hot putting foot down it can be slugish other times its perfectly fine.
I have done a major service on it, replaced all vacum hoses, cleaned throttle body, cheched intake for leaks, replaced pcv valve and hose, and cleaned icv thoroughly plus checked it operating. I notice when unpluging icv the car generally drive's happier and smother except the fact it idles high (1300rpm)when warm cause mixture rich but then again the rich micture might just mask the problem to begin with.
Not sure weather to start looking in to Throttle Position Sensor Or Possible Fuel pressure issue?
Was also wondering if its normally to have slight ticking noise from Injector area not sure exactly where tho? dosen't appear to occur alond side with idling issue
Here are some more details on the car:
1994 318i 4dr Sedan
M43 with 5sp manual
Chassis number KB00773
Just done 200,000kms too
Willing to chuck $20 bucks someone's way if they can help me out
