Try checking for vaccum leaks, use carb cleaner and spray it around the base of carb, vaccum hoses, edges of intake manifold, take pliers and squeeze the big line to brake power booster & see if it changes, pull the pcv valve out and cover with your finger see if it changes idle.

Code 23 engine idles but surges when in gear

Replace the Intake Air Temperature Sensor.
Depending on your size Engine (2.4L, 3.0L or 3.3L) It should be located where the Air Filter is. When you take the cover off, it wil be mounted into the cover. It has the only wires going to the cover.
This sends information to the Computer which adjust the air/fuel mixture - causing surges.
The 2nd recommednation: to remove, clean and check is the Idle Air Control (IAC) Valve and replace if necessary.

Let me know if this helped....

My 2007 veracruz has a shudder when starting in 1st gear and when shifting into second. Also have a pulsating in 5th and 6th gear at 1400/1500 rpm.Seems like the car is lugging in 5th/6th gear. Could this...

Mine had a *bad*, but intermitent engine shudder (like it was running out of gas) between 30 and 40 mph. After 3 trips to the dealer, it finally did it in front of them. It's quite dramatic, so they admitted that I wasn't just bringing it in for fun and started guessing what was wrong. They found a TSB that recommended starting with one of the O2 sensors, which fixed it perfectly, immediately.

Sounds like yours isn't your engine - but I thought I should say something just in case.

Ok there are several options such as water in the fuel or dirty fuel for starters. Another option would be clogged fuel injectors or a dirty map sensor. Check the spark plug wires to be sure that they are on tight and none are worn at contact points such as rubbing against a sharp edge. Let us know what the code(s) say.

MY 1989 chevy silverado pulsates or urges in Idle. It allso does it from zero to 35mph then smooths out. problem is intermitent.

My fathers did the same thing. we soon figured out that the injectors were not making an even mist of fuel they were just dumping the fuel in. we replaced the injectors and the problem was fixed.
