rough idle and MAF or FPR 850 1994

posted by  someone claiming to be tapsa on  Tue May 9 06:41 CST 2006 [RELATED]

Hi,
today I measured the FPR and it shows 2.9bars ie. close to 3bars I expect to be nominal.
I also cleaned the injectors and their mountigns without noticing any abnormalities by looking.
Then I swapped the fuel ECU which did no difference.
Claus, last saturday I took a high rpm (4000) for 15 minutes to clean up before oil change but did no help.
Now as new 'feature' I have with warm engine idle speed 1100-1200rpms if turn to N or P but then on D it comes down to 1000 but is rough in running.
On the week end it gave twice 1-1-3 ie short term fuel mix weak.
Any conclusions? My latain starts to be out...Tapsa
