Hi all, I'm at a loss on this one. Did a head gasket on an '03 Altima. Ran great for a week or two. It's now running rough on acceleration. Idles fine. Even in park, slow and constant acceleration with no load gets some hesitation. No check engine light is being set. Hesitation is hard enough that, when driving, the car struggles to accelerate up hills.
I'm used to something like this setting a code, and this is baffling me. New coils, spark plugs, cam sensor, and it was running fine.
On the head gasket, recall the car ran fine for a couple weeks. There is no bubbling in coolant, no overheating, head was milled, and Fel-pro gasket used, all work done right. Remember it ran smoothly for 1-2 weeks before we started having this issue.
No codes with rough acceleration is the key. What could cause that?
Thanks!
Filippo
