Miss on acceleration
My 2008 ls has developed a miss on acceleration and gas mileage if off 25%. To start in the morning takes 3 tries exactly. Has 80k. Plan to change plugs and would welcome any ideas as to cause.
Thanks
John

There are a lot of things that can cause a random misfire.
There is a tsb for carbon build up causing a random misfire on the 2.4 engine.
I would start checking the basics. Fuel psi being my first test.

May I concur with these suggestions and throw in a dirty throttle body! Or battery about to expire! Or loose ground wires! The infamous low oil level?
Please check these suggestions and get back to us.

I see from searching the forum several cases like mine where the fuel pump was the cause. I will go get the codes read and try to get a test gage for fuel pressure. Is there a fitting for this on the fuel rail?
