what could be causing the hesitations in my accelerations? I'll start off and it feels like my car just doesn't want to go, then i'll feel a little jolt and the car starts to accelerate. My engine is just a D15B1 with no VTEC

Whens the last time you did routine maintenance on the vehicle ?

 

I just did a tune up and brakes done on my car and it still does that same hesatation thing.

BTW my motor is a D15B2

What did you change ?

 

Sounds like a timing issue to me.

 

I thought maybe it was dirty injectors

 

Sounds like A honda problem to me... no torque mine does it too.

Ha... jk well I would say timing too... how hard are u hitting the gas when it hesitates.

 

It usually happens in 2nd gear and I'll reach halfway down on the gas before the motor will go.

 

Do you have an automatic ?

 

no its stick

 

Well I would do a routine maintenance on the vehicle, plugs rotor, wires, and fuel filter. Then go from there.

 

thanks for the info. How do you check the timing? Haven't done that yet.

The way you describe it there sounds like you may have some slack on your throttle cable, check that out it's easy and will take 5 mins to fix if it's too loose.

Other things...Air filter, fuel filter, etc.

Try one of those fuel system cleaners that you pour in your tank before you fill up.

Check engine light on your dash at all?

I did about a thounsand miles ago (fuel system cleaner(Prestone)) and it said that it protects for 12,000 mi. No check engine light.

The fuel system cleaner you add to your tank really does not help, you need the ones they use at a real shop or dealer, where you car runs off fuel cleaner alone.

 

Maybe you jumped a tooth on your timing belt? or it's just out of wack.

Here's how you check timing...First of all you need a timing light/gun

1) There's a connector on the right side of your engine bay near the edge of the front fender (i've heard some are on passenger side near fender). Take off the little yellow cover on it and place a paper clip with one end into each hole (this jumps the connector grounding it out, ECU now is unable to change timing itself).

2) Hook your timing light up to (+) terminal on battery and ground the black wire then the 3rd (sensor) wire will connect to your #1 cylinder wire (one ran all the way to the timing belt side spark plug).

*also loosen the distributor bolts enough so you can rotate the distributor by hand.

3) now start car (idle may be lower), and aim gun down at belt pulley. You should see a plastic sight like something that's on the barrel of a gun for you to aim. Look directly along the sight an you should see some markings flashing on the pulley

4) White line is TDC. Red line is where you want it, so slowly turn the distributor untill the RED line is directly seen through the site in line with it. Then tighten the distributor.

Turn off car and remove paper clip from connector. Remove timing gun. Start car and drive around and see how it feels.

This is how i always do it...

Good luck!

they ajusted the timing, changed the spark plugs, air filter, and other routine matinince.
I'd check your fuel filter first and presure. your injectors could also be dirty.
