I e tested 4 now and after 10 min none of them close completely or at all. Either way could it be because of a bad connection? Not hot enough? I know atleast one, the newest one was tested as good and is very clean. I know they can go bad inside but I do not think they all are.
But after 10 min of car at idle its still pulling air thru, suggestions please. Phil |

Take the AAR hose that goes to the air cleaner off after it is hot and surging. Put your finger over then end. This closes off the air that would cause high idle. If you still have surging ( and I suspect that you will), then the AAR is not the problem.

Tom (IMG:style_emoticons/default/agree.gif) What is the current status of the MPS in use? good question- i got the current MPS in a parts buy , tested by me on the vac-it hold vac, but the epoxy plug has been removed and someone has tried adjusting it, its been apart im sure, but the looks of the fasteners used to hold the 2 parts together. - my other one i had i sent back to Ecklers- Scott and i have discussed this already, on club site, and i was going to sent this one to you to set and check out but i have not got the one back from ecklers- had it for 6 months but after fighting surge, i bought a vac tester, and sure enough it failed so i called them , sent it back- that was in may- they are on "back order" from Fuel Injection Corp. in CA so i am sitting here with a questionble MPS- holds vac but..... and the other- i called and told them if i did not get it replaced by the end of the month i wanted my $299 back and my core i sent them. ( we'll see how that goes) so if anyone has a tested good 75 2.0 d-jet MPS i can try to see if that is it i will by if it works!!! but the AAR is still sucking air when hot- i know they are supposed to get hot if element is working- when i plug the end the idle immediately drops, almost too low, - i know i am fighting mixture and that might be the MPS now that i consider that it needs to be calibrated and someone might have messed with it without knowing how to do this. Thanks for the help. hey Eckler's(automotion) (IMG:style_emoticons/default/slap.gif) (IMG:style_emoticons/default/slap.gif) |
