Simple and short. Just picked up my car today with new engine. Car has no power after 5k rpms and my shifter get stucks near the 5th and 6th gear box.

Take it back to whoever did the install and have re work it. Make sure everything got hooked up correctly.

You're from Long Island NY ?

if so, dont tell me you did it at Great Neck Mazda.

they might tell you it's normal...hahaha

lol the prob pinched the harness.. happened to me when i got the flywheel instaled... car eventually began to stall.. take it back because that is what more than likely happened.

I took it to the Garden City Mazda . Mind you my car has been there since April 23rd. Plus before they replaced my engine they charged me 1062$ to change my spark plugs, spark plug wires, battery and coils. Ridiculous !

And the only reason I paid it was because when I told them the price was outrageous, and I'll take my car somewhere else. They told me I would have to pay a 260$ Diagnostic fee. Plus 50$ everyday the car was there, and towing fees to get it back to my house...

So tomorrow unfortunately I'm going back there for them to take a look at it.

I would punch them in the face.

STOP TAKING YOUR CARS TO DEALERS THEY ARE MONGOLOIDS.
