Hi there,

Got a stuip question and nned some one to give me an ID10-T Class.

I just bought an 03 Ford F150 FX4 crewcab Lariat model. Anyway sometimes it seems the $wheel drive works sometimes it doesn't Ie I can hear the transfer engage truck moves at a crawl but front tires don't move.

So I did a search hear I found it could be a number of things. But here is the class I was wondering if some one could give me. What are the steps for putting your truck into 4 wheel drive IE. put into park then move switch or while moving under 5mph move switch. Any and all Instruction will help.

Also about a month after I bought the truck. I noticed that when I cranked it up the RPMs would shoot up to about 1500. Then come all the way down to about 300 it would do this about 3 of 4 times.
Does anyone have any ideas as to why.

I took the truck to a Ford dealership to have it worked on. Well 1400 dollars later truck is still doing the RPM thing. I had them change all the fluids and spark plugs also they had to replace the COP on 1 and 8.

Thanks again for your help.

 

not sure, but try the IAC (idle air control) valve, for the rpm problem. its probably a 60 dollar part at autozone or napa
