hello everybody, i have a 96 GC laredo that i just bought a few days ago with 4.0 and it runs real rough when you first start it up in the morning, it kicks and bucks like crazy and you can't give it any gas. after about 15 minutes of this it clears up and runs great for the rest of the day. unless you let it set for several hours. i just put a temperature control sensor in it but after it set for a few hours back to square one. looks like someone just put a new distributor cap on. any help would be greatly appreciated. thanks!

 

When you first started it spray TB (throttle body cleaner) around the intake manifold gasket, where it meets the head. Could be a intake gasket leak that seals up when it warms up a tad.
