burning/waisting fuel and no acceleration

[ray719]

So I recently had to replace my f22a6 with an f22a1 and now that I have the car running again I'm noticing little to no acceleration and there's a strong stench of fuel and high amount being used. I'm currently running headers and down pipe till I can get the flanges to insert a test pipe. I am still using the a6 computer. What would be causing these issues?

There are many things.

Check for codes first.

Does it go past a certain rpm or does it just bogg?

[cloudasc]

OP, is your car an automatic or manual? If an automatic count how many times the car changes gears to get up to highway speeds.

Also what year is your accord? If you have a 90-91, is your sport light on all the time? If you have a 92-93 is your d4 light on all the time?

If you have a 92-93 is your d4 light flashing all the time?

Fixed.

How do you waist something?


Spelling nazism aside... Have you checked the valve timing on the F22A1 to be sure it's correct? You should always change the timing belt when installing a new engine, unless you are certain that it's already been done recently.
Also, a lack of power and poor fuel economy are often attributed to a bad o2 sensor.

As for running with an open header... that's a great way to burn up your exhaust valves.
Get a proper cat. Don't use a test pipe. Your car will sound awful, smell worse, and kill the environment... which will eventually lead to even stricter legislation against our hobby.

It's a manual 92 it originally had an a6 but currently running an a1. I'm gonna check timing again but I had 2 cels yesterday o2 senser and map I fixed a few vac lines and got that fixed but than today my fuel supply system light came on (cel 43) and its still eating gas I've killed half a tank in 58 miles

[deevergote]

Code 43 is most often an o2 sensor code as well (I've only seen one instance on here where it was not.)

Replace that o2 sensor with a new Denso or NTK unit (no Bosch, they don't work), and replace that MAP sensor. That should definitely fix your problem.

If your base ignition timing is too retarded, that can be a source of wasted fuel, as well as a performance loss. It wouldn't account for your half tank in 58 miles, though.

[ray719]

now i have no fuel pressure could my fuel pump have caused all these problems im having such as burning extra rich lack of power and using extream amounts of gas

[accordztech]

if you have no fuel pressure then how could you dump all that fuel?

[mtnbikaah]

maybe you have a leak in your fuel line.

[ray719]

It did have pressure till Saturday afternoon I checked yesterday and still nothing but than this morning it fired right up

[evil_demon_01]

How did you find it had no fuel pressure? Check and repair the main relay to fix that.

Though that is a separate issue to using excess gas.
Have you changed the O2 sensor as has already been said?
