[QUOTE="Kevin Palmer, post: 631947, member: 54263"] As noted above, your IAC probably does need to be cleaned as it is a common issue with the Trac. My guess is, that your AC charge is low and the compressor is cycling on and off as a result of the low pressure. You notice it more in drive as there is a load on the engine from being in gear. In park, no load so the Idle drop is not as critical to how the engine is running..... [/QUOTE]
