High idle
I have a 2 part question for you all.
2 days ago my 96 D1 started acting a little strange. When i start it up the rpms jump to around 1500 and it just ides there. I give it some gas and the rpms raise and then drop right back to 1500. if i switch it into gear the rpms drop down to normal. around 600-700 rpms. this has happened beofre and usually turning off the truck and restarting solves the problem. however that is not the case anymore. it does it everytime i start the engine.
i checked the IAC and claned it it seems to be working fine, i had guessed it was not the IAC anyway because i cleaned it a few months ago. I also removed and checked the TPS it was not dirty and was functioning ok.
while i was poking around under the hood i started the engine and let it idle and gave it a little throttle a few times to listen to the engine. i found that after i would throttle up and release the engine would bog down to like 200 rpms and falter a bit. I also noticed a new engine whine noise. i go tmy stethescope out and found out it was the alternator, which by the way is he 4th rebuilt alt since late january. i had noticed a bit of increased whine noise over the last few weeks but had assumed it was just, worn difs, trasfer case etc.. but no its the alterntor. after isolating the whinning i turned off the engine to check the alt. connections. as i got my head over the alt i could smell a distintive burning smell coming from the alt.
So granted i need a neew alt. but would a failing alt give me idle problems like i described? if not what else should i check?
Now for the 2nd part. i am through with rebuilts. I can now swap an alterntor out in 15 minutes thanks to all my "practive" but i am tired of doing it. What would yo uguys recommend for a new alt? mean green? New magna marelli? let me knwo yer opinions and where i can get one at the best price.
thanks for your time.
