Hesitation @ 2700 RPMs.
Has anyone else noticed some hesitation, when accelerating, @ 2700 rpms? I never noticed it before but now I do. It only happens when I have the A/C on though. I used to have this same kind of hesitation when my old toyota had bad plugs and was misfiring. The hesitation feels like if you let off the gas for a split second while your accelerating.
I'm not sure if it's an A/C thing or if it's a bad spark plug. The weird thing is that, if it was a bad plug, there is no CEL. I'm just looking for some quick suggestions before I go giving the car a complete tune-up. Edit: Sorry...The hesitation happens at 2700 not 3700.

I had that hesitation and the ECU recall fixed my problem. Mine was at 3500-3700 though (I think) but it was exactly like you say. It happened with a/c and with no a/c. Take it to your dealer and see if you can talk them into the ECU reprogram recall.

I have been able to get rid of the hesitation with no A/C, or maybe just reduce it enough to negligible, but whenever the A/C is on it is very noticable. For me the reprogram didn't seem to help.

After the grounding mod....My hesitation is GONE. With new plugs, an oil change, and the grounding mod, My car is smoother now than the day I drifted out of the dealer's lot.
The grounding mod is a MUST do. One guy used old lamp wire and got rid of the hesitation. do the mod now. your heavy foot will thank you later! |

It's less common with the '02s, but we still get it. Grounding mod is your best bet. Look up the "SPG" thread.

Not only use the ohm meter to measure the resistance with the key off, but also measure the voltage from two ground points while the engine is running.

Off the topic guys
Uhh, guys? He said it is when he has the A/C on. The hesitation he is getting is when the clutch on the A/C engages and disengages. When you get on the throttle, the clutch reduces the load sent to the A/C system pully to give more power for accelleration. This happens on my car and my fiance's Legacy Outback. I truly don't think the hesitation issue he is having is a grounding problem if it only occurs when the A/C is on and doesn't appear with the A/C off.
