car wont idle after motor mount install

[petey882]

hello have a 90 eclipse and was running excellent went to my fathers house and installed my prothane mount inserts and got done car started up and ran fine drove down the road to go home and got to staop sign and car died.... it starts back up just fine but will not hold idle..... car ran just fine 2.5hours before i did the motor mounts.... nothing was unplugged except stiock MAF and speed sensor on the tranny..... fuel pressure still at 38psi.... car runs fine except wont idle no spitting and sputtering or anything just no idle.... any help would be great this is my daily driver.... i have checked all vacuum hoses and all plugs.... one thing i took my wastegate off to get to the fron motor mount bolt and when i tightened the bolts back up after putting them on i noticed the turbo twisted about 1/8in downward when i cranked on the bolts to tighten them but dont think that would cause my problem... PLEASE HELP!!!! also not gettin a cel at all

could my throttle cable have gone out of adjustment..... i took the cruise box off to get to the motor mount below it i did not disconnect the cables the just took the bols out and set it to the side.... i can barely hold the pedal and make it idle fine so just wonderin if that could be it

Have you tried un-screwing the BISS a little to see if it'll hold an idle?

no have not messed with anything yet it was running fine before i installed the motor mounts dont know what happened.... i unhooked the battery and unplugged maf and speed sensor and thats it

If it sits any different or the line is pulled any or loosened any then it will cause a little idle differences, check you idle adjustment. make sure everything is set back right and where it is supposed to be, that would be my first check.

yea motor sits a little different now bc all the mounts were pretty busted got the new prothane mounts in so its where its supposed to be now ima try to adjust the ilde screw and the cables and see what that does

Could be any idle issue now, sometimes we change things then something random happens, you never know. Recheck everything and go from there but the link is a great way to look for things related to idle.

k wel turned the biss screw out and it idles fine now should i leave it alone and call it good or why did i have to do that doesnt make sense how it was runing fine before.... i havent driven it yet to see if it still runs the same but it does idle now

Make sure your MAF is hook up properly.

Some times it get loose. Saying that you only unhook the MAf, Then It more common that it is not getting the signal.


Check your MAF Connectors,

if the maf wasnt hooked up wouldnt i get a cel...... it seems to run fine now it idles fine ive drove it around it almost seems to run better than it did before while driving... anybody live near charlotte,NC pm me lookin for some fellow dsmer's around me to help me out some

Sounds like you got it figured out buddy. No more instruction needed. Sometimes you just have to adjust something. It could have been at the previous angle the MAF sat a little differently or something just a hair different. Regardless the problem is fixed now so you should be fine.
