my car is poop!

[rafoda3rd]

I'm getting really pissed that my car does not run like other cb7's. i've upgraded 2 tyhe h23 intake, a6 head, cold air intake, pt6 with black box, rae disc brakes fuel pressure regulator, high flow fuel pump. And my rpms barely reach 6200 rpms. my car has no black smoke or blow by, does run a little rich since h23 intake. when the rest of the crew reaches as high as 7500 well pass redline. my car feels like its got no ass... compared to stock a6 motors. W T F do i need 2 do or check, to resolve this. tried upgrading but only 2 have problems with fuel now...........keeps shutting off...

What kind of fuel pump, and fuel pressure regulator did you purchase? Check your fuel pressure at idle, it should be somewhere around 38 psi, I believe?

Also, check your timing with a timing gun, check your cap and rotor. How old is your O2 sensor? Etc, etc, etc.

autoteq pump and regulator the car has full maintence except for distrubtor.but i have swapped it with others including coil.

[JesseXC]

Just a question, with those mods there isn't any tuning needed?

[rafoda3rd]

its nothing special other than upgraded stock parts for little boost in hp.

However, if you have too much or too little fuel pressure due to the regulator adjustment, your car will run like "poop."

There is absolutely no reason to run a high-flow pump on a stock motor. The motor doesn't need that much fuel. The fuel regulator I could understand if you had a high-lift camshaft.

Like I said, check your fuel pressure at idle. It should be 38 psi.

Fuel pressure is a big one... make sure that regulator is good, and maybe change out that pump for another brand. Honestly, I never heard of that brand. Walbro is what most people use, and the stock pump works just fine in most cases.


It could also be a power issue. Try replacing the distributor, and everything inside of it. It'll be money, but worth it. It's old enough to warrant a replacement anyway.


Also, when you swapped the head on, are you SURE everything was lined up properly? All timing marks are where they should be? If you're just a little off, it could make a big difference.


Also, how about your ignition timing? Have you checked that?

Yea as has been posted, check your fuel pressure.

No there isnt any tuning involved with his setup.

If you expecting this much from those bolts ons, you might want to look into a swap, boost, or juice.

The F series motors are awesome and do breathe easier with the bolts on and changes mentioned, esp with the a6 head but it only takes you so far.

Also, it really SHOULDN'T rev past the redline. It can, and people do... but it's not a fantastic idea. Aside from the engine design, these engines are OLD! If your bottom end is bone stock and original, as well as those valve springs... you can't expect them to hold out with that kind of abuse!

lol most people revving to 7500 rpm are not running f22a. ONly a few rev that high. For one a pt6 wont even let you rev to 7500. And most people have at least a cam to back it up with a tuned ecu to rev there.

[AccordWarrior]

I've been reading more and more that valve adjustment is key as far as maintaining the power levels that the car had originally if nothing else.

My Mom's bone stock F22a4 had a valve adjustment right before we got it and it definitely was much quicker than my I/H/E F22a1.

I know that the I/H/E on my car gave me more than enough HP to equalize the motors as far as that's concerned. However, I hadn't adjusted my valves in the 50,000 miles I owned the car.

reving the motor, while in neutral, not while your shifting gears (driving) is what i meant. the car ran like poop in before the bolt ons. had a little stutter and also my reving was way slower than everybody else. but anyway the car took a dump its parked until my stock oem fuel pump assembly gets in. i'm swapping the P O S thats in the tank. i wanna thank everyone for there help and replys.

[deevergote]

You would rev as high as it would go in neutral? Are you nuts?

[NAiL05]

You would rev as high as it would go in neutral? Are you nuts?

or retarded one of those.

[Ralphie]

Neutral!?

Why?

That does not determine the potential or power of a car....it just gives you more things to fix.

Don't do that anymore.

OMFG.
