flatblackvw Okay so today I pulled the throttle body and IAC since they seemed to have quite a bit of build-up, I cleaned them all to basically looking brand new and im still having the same issue. Any advice on what to look for next?

and yet again, thanks for the help.

Shelby427 Yep, all you are doing by holding the throttle is getting it past the idle circuit. Ain't like a carb where pumping the pedal adds more gas.

Pull the IAC, clean it real good, and also spray carb cleaner into the port the IAC goes into. Then open the butterfly on the throttle body, look for a deposit ring around the bore, below the butterfly. More carb cleaner, and a toothbrush if it's really stubborn.

Watch when you reinstall the IAC. If you bugger up the O-ring seal it can bind the IAC pintle valve and you'll have all kinds of idle problems.

Black98 sounds like the Idle air intake system is dirty and could use a good cleaning, this is located within the Trottle body if i recall and you should use some cleaning product to clean it out good and clean the rest of the TB and intake manifold while your at it.

Curro Take it over to Advance or Autozone and get the alternator checked...

flatblackvw I went in and cleaned some corrosion off the battery terminals and checked all the connections which ended up being fine. Tried again and had no luck. After messing around with it some more, I can start it everytime with some help from the gas pedal, and when its on I can keep it running as long as I give it some gas the whole time, if I let off the gas it will idle for a couple seconds then die.

Im thinking the fuel pump and filter should be the next things I check, does anyone have any other ideas or possibly something im overlooking?

again thanks for the help

Shelby427 Battery cables, terminal ends, ground connections. All have to be clean and tight.
Common problem on jeeps. Any would cause a weak start, slow crank, and if bad enough a break in connection to cause the stalling out.

starting problems

So im familiar with cars and forums and I have searched but dont really know what to look for...

my roomate has a 98 TJ and earlier today it began starting slow, as in it wasnt immediately starting when you turn the key but a sluggish start but after it would run fine. Later tonight we went to drive and it started with help from the gas pedal but as soon as you would start to drive it would shut off. My first guess was the starter was going but when it started stalling out it seemed to me like a dead battery but when its trying to start its not clicking like most cars do when the battery is dead, and the volt gauge reads 14 volts. Im wondering if this could be an alternator, or air/fuel problem, and if it is any of these things will there be other signs to look for (there are no CEL, or other warning lights)?

basically im looking for any help to point me in the direction to find out whats wrong, im very familiar with fixing cars and can test different things but im not very familiar with jeeps and im just looking for insight on where to look first.

TIA
