I've been having this problem for some time now , I've talked to other ppl got opinions , got the batt replaced because it was bad didn't fix it , then tested the altn tested good , changed out the belts , a/c really needed it the serp. was ok, but did it any way and changed out the the stationary idler pully it help out some , but it still bogs down. What I mean by this is that the lights dim even inside the dash and radio , and the a/c even slows down I guess the blower motor isn't getting enough juice ? The only thing I can think is that either my timing chain is going out or its my pos. side battery cable its a lil corroded so I'm getting that just a precaution . I did spin the alt. i'm not sure how freely the pully is suppose to be but felt a lil tight in my opinion.

My car is all stock besides the battery and wires .

 

There are many reasons.

 

atleast two sides to every circuit. get a meter and start metering spots. your lucky its affecting everything. it should make it easier to find your dirty connection. try grabbing a set of jumper cables ,putting them on the negative , then ground the body cleanly. you may find it to be a simple solution.

 

what you mean to sides to every circuit ? what you using the ground cables do ?

 

sounds like you have a grounding issue

 

i would honestly take it to a mechanic if i were u. cause it seems like u have no clue what u r talkin about.

 

honestly I do to a point , when it comes to electrical Im clueless, I'm learning as I go , and I have taken it to several and they tell me to replace the positive cable , if that doesnt fix the issue then do the alt. then if that doesn't fix it then do the timing I'm like well hell

 

good luck

 

some times I think it will be easier to just get a crate engine with every thing new replace all the wiring then I will know every thing is right

 

there is a positive and a negative and each are equally important. if you have allready replaced the positive cable there is only one suspect left. the negative cable is a temporary substitute for your main body ground. and if you want i can take your old motor when you get a crate motor.

 

well im going to order it and see if that helps hopefully it does, but what gets me is im having a random misfire with no codes and whats weird is that it really doesn't do it when I have the ac on could it possibly as simple as the timing chain?
