Acceleration

Asked by May 29, 2016 at 05:02 PM about the 2007 Chevrolet TrailBlazer LT 4WD

Question type: Maintenance & Repair

Hello, please help me. No one seems to know my
problem. I have no check engine light, no codes.
Changed my spark plugs, fuel pump, fuel filter,
thermostat, air filter, throttle body. I lost count.
Transmission fluid and filter. My car has 70k miles
and it doesn't accelerate the way it used to. Each
time I put my foot down on the gas it accelerates
differently. Mind you no matter how fast I was going
highway or not, I never had to pass 2k rpm. Now it
goes to 2500 to shift so I can hit 20mph. When I hit
the gas my revs climb and my car goes nowhere
but when I remove my foot and hit it again it'll go
like it used to or it'll downshift and launch. Me being
at 1/4 or 1/3 the most on the gas. On the highway
my car doesn't seem to want to pass 2000rpm at
70mph it's like limited. Please help me. Car had 29k
miles last year and all was well until I got hit in my
rear wheel and my axle shaft was bent so it had to
be replaced. Do you think this can be a misaligned
rear axle or a bad rear differential? After the repairs
when I hit the gas my wheels span and I heard a
loud crunch in my rear differential. But I have no
whining. Maybe a very very very low purr

Loud crunch? That's where I would start looking first. Have rear dif inspected.

I also just got p0304 cylinder 4 misfire

Can this cause my car to go in limp mode or can this drastically reduce my acceleration?
