Hello, I am having problems with my 2000 Explorer Limited AWD V8 starting and sometimes after I get it started it wanting to stall out.... also when acting up this way it doesn't want to idle and I can rev it so it will stay running. It will turn over with all systems doing fine but won't start , sometimes I can punch the gas and it will start but I cannot say weather doing that helped or it would have started anyway. Well... This is sounding like the IAC valve and throttle body needs cleaning to me does it to you ?
Is there more to r&r the IAC than meets the eye because I have got a ~$200 est. from local ford dealer.......also a local mech shop said ~$100 that to replace it takes 15 mins plus the part cost.....if it only requires removing the part and replacing I would like to attempt that myself but a few years back I quit doing much work on vehicles ....but wouldn't mind getting the satisfaction of fixing again.
so local mech shop says that the IAC won't prevent it from starting only cause it to stall out once started?? ---is that correct?
Oh BTW, Local shop read the codes after I was in the mountains on the July
4th holiday and the check engine light came on for 5 days but before I got it to him it cleared after one morning starting it seemed like all the sudden the idle and all straightened out..... the local shop code reader said some things about possibilities but nothing conclusive....he also swapped the relay on the engine fender for the starting with the blower one as he said sometimes the contacts get pitted in attempt to troubleshoot....... it ran good for a week or two then it has started acting up again. It always does it after sitting a long while, such as overnight, also it now will sometimes want to stall out when I am driving down road which it didn't do before.Sorry fort the long post but I am trying to give background info to the problem.
I have had the spark plugs changed in the last year. I also suspect the MAF sensor but I have never attempted to clean it.....would that item be involved in this problem too?
thanks for reading, please advise. Bill V.
