Vibration again what is it this time HELP!!
 

Ok so the vibe is back with a vengence! Just finished the Mazda zoom zoom engine decarb and everything went smooth? But now for some reason the car vibes alot more in drive at a stop light and when I turn the AC on it gets even worse now!

I just replaced
engine mounts
spark plugs
wires
cleaned the MAF sensor

Added
boost brothers header
rx-7 store mid-pipe
mazdaspeed exhaust

Bump

Bump

errr... engine mount again? the dealer can easily figure it out. badly installed plugs?

I installed my own plugs using the DIY maybe I did somethin wrong I'll check on them!!

I also noticed that when the car is warm and I try and start it, it takes awhile to start then the RPMs drop really fast like they barely reach 1100 rpm then drop to 950 this is to weird!!

Ok so I tightened the spark plugs and the problem still lives on but now it's worse
When the car is warmed up and I put it into drive it will climb in rpm jerk forward then the rpms will drop to 950 and the car will vibrate like crazy any input or experience with this issue?

There are two types of plugs. Did you install them correctly?

You have auto?

Yea an 05 auto
I jus took the throttle body out and cleaned it and the problem is still there!
When the car is warm it starts to vibrate really hard when In drive and reverse

check motor mounts again

Is it a posibility that they installed wrong? It seems so simple just mount the and srcew the bracket back in! But I'll check em again 2marrow!!

maybe they just failed again, if the problem is only happening when you're in a drive gear then that makes sense..

bad coils

Update: Checked mounts no cracks and the middle is still good!
I checked the coils with a timing light and they all were good the first time I checked it I wasn't sure if I did it right so I had my friend check em and got the same outcome and he said they were good!

When I put the car in drive the rpms jump really high then the car will jerk forward then it will vibrate really bad this is annoying me Im getting my plates 2marrow so I'll probly drive it to the dealer this weekend

Well tell you what, I had some where around 60k miles on my 8 seafoamed her and changed to synthetic oil. Started getting hard starts but could still wheel cherp 1st-3rd. The car would vibrate really bad. So I took her in to have a compression test done and what do you know. I need a new engine and I'm running on one rotor.
