...my new engine!!! Its off a 99 Elantra and it has bout 70k miles on it! Wilbur and myself picked it up monday nite (it was supposed to be done sunday) cuz when they put the engine in and got everything hooked up they found out it had an oil leak coming from the oil pan gasket which I guess is pretty common on the Elantra engine!?!? Anyways, picked it up and they're like well it doesnt leak oil anymore but its running really rough! Turned the key over Wilbure listened to it told me to pop the hood and he fiddled with the MAF and the noise stopped!! Cause it had been sitting there at the junkyard for awhile the HLAs were kinda loud, but after driving it for a day its so quiet now, my idle is once again smooth!!! I am sooo excited!!! Except yesterday (tuesday) I go to leave for work in the morning and it starts to run really jerky (didnt get more than two blocks away from my apartment) so I decided to turn around go back home, you see after the oil leak they couldnt get the CEL to turn off and yesterday when I went to go to work the CEL stayed on but when it was jerking it would flash on an off! So once again Wilbur came to my rescue and come to find out one of the fuel injector clips was not plugged in all the way!!! So we plugged it in and it ran fine (CEL still on) we take it to Schucks to scan it and just because of one injector clip it was throwing 6 other codes so we cleared them, put sum Seafoam in and it runs sooo much better!!! I love it!!! I do have a slight exhaust leak I guess which doesnt surprise me (that car has had like 10)!! But now I really need to make it up to Wilbur for rescuing me once again!! Any ideas, maybe dinner dont know!!! LOL!!! Im just happy to have my car, and I actually made it to work today even with an extra 300lb from my old engine!!! Wilbur is taking mine and were gonna rebuild it and put it in his Elantra! Im sure he is excited!!
