I have a 2000 maxima gle with 167k miles. The car is in mechanically good shape. No real problems since I bought it 4yrs with 100k miles. I decided to do a tuneup but now the car is shaky when in gear and when its just driving off. It Idles fine I cant seem to understand what it is. I know I have to replace the O2 sensors but that shouldnt have to do with the car shaking. I replaced all parts with oem nissan parts.

 

Exactly what parts were replaced during the tune up?

 

I take it he replaced the plugs, and in the process, prolly didn't seat a coil good enough.

Also, whats with all the advertising spam links in your sig?

 

I replaced the sparkplugs pcv valve, filters

 

+1 VQPOWER

 

look for un-plugped vacuum lines, in case u had to take any off. In addition to shaking, ECU could throw a code. g'luck

 

Did you check the gap on all 6 plugs before installing them? Sounds like a misfire you didn't have prior to working on it. First step...Double check your work.

 

when in gear and you're idleing whats the rpm at?

 

i think you the have an undetected misfire, soon your ecu should throw a code for it, but check the harness clips for each coil and also make sure they coils are on nice and snug.

 

ok I will check the coil packs to see if they are all pressed down. Thanks

 

Had a similar issue with my 2K and found I messed up a coil pak when I removed it. They get somewhat fragile after 100k miles.

 

Check for spark plug gap...coils properly seated and connected properly...vacuum hoses properly connected and no leaks.
