I need help! 2001 trooper 3.5L 4x4. Rough idle, Runs rough when driving. Randomly just dies! Put on computer, says it's throttle body assembly. I didn't replace whole assembly but did replace throttle position sensor. It didn't help. Replaced egr, muffler, tps. Nothing is helping. Pls help

^ Also, get a squirt bottle full of gas and spray it around the throttle body to check for vacuum/ gasket leaks while the engine is running

What EGR did you use for replacement? Have you ever cleaned out the EGR outlet tube in the intake? What are the codes?
I bought oem egr. Blew into tube but didn't get into the intake. Codes were for throttle body replacement and tps .but only changed tps. But that was on generic AutoZone computer. Generally vague!
