Car has trouble starting and when it starts it bogs when I floor it. If I ease in to it, it will come up to redline. Its a stock HF with a fairly new Distributor w/10k ,new spark plug wires, new FPR, new injectors, new fuel filter & TPS? I cracked the fuel line and it squirts fuel? any ideas? No codes?

F22Master

air filter? did you adjust the tps properly?

HT Chaplain

I try calibrating the TPS

Do you have a spare O2 sensor lying around? I don't know what to say exactly. It could be your FITV, that causes stupid problems. It sounds like too much fuel to me.

DCRB

did you use hf specific injectors?

HT Chaplain

TPS is calibrated, injectors are correct

HT Chaplain

the back is covered with soot as it started running bad right before it died. I thought and it looks like it has been running rich prior to not running at all. thats why I replaced the FPR and injectors. Didn't change a thing

Pull your spark plugs and let us know how they look.

HT Chaplain

black sooty spark plugs not wet

DCRB

hmmmmmmmm do a compression test. do a valve lash adjustment lately? could be too tight.

My guess is a weak ignition.
I didn't see that you changed the plugs with all the other tune up parts.
Maybe change them out and all will be well again.

What wires are you using?
Are you using a new OEM FRP?

If it's weak ignition, spark plugs are a very cheap fix. Does the ground on the valve cover have anything to do with the ignition system? I hear people having a lot of problems if they delete that ground.

There are 2 ground on the valve cover area. One gets screwed down to the valve cover itself and the other hooks onto one of the valve cover posts.

The one going to the post does help grounding for electrical/ignition functions.

The other, bolted directly to the valve cover, serves an anti-corrosion purpose. The valve cover is insulated by a rubber seal and rubber grommets. Not having metal to metal contact with the rest of the engine can give it a difference in potential so they add the ground to manage electrolysis. Other types of cars often have a ground strap going to the radiator that serves the same purpose.

Alrighty. I have both of mine. They are right next to each other, but one connects to the post and one is just the valve cover.

OP, definitely check for those. Could just be a dirty ground.

I beefed up my transmission ground and deleted the valve cover ground. it isn't all that important. i get the electrolysis explanation, makes a lot of sense... i just see that as a minor thing compared to a non-running car ha ha.

Any time I've had this issue it has either been...
TPS (integra guys have had luck switching the red and yellow wires).
Oil seals for the spark plug tubes, getting oil on the spark plug wires and causing them to arc and not spark the plugs at proper times.

Switch out the spark plugs and then try adding a ground temporarily with jumper cables or heavy wire. Go direct from battery (-) to the trans, valve cover post, a distributor ear... any or all of those! Even with your trans ground beefed up, ground still travel from the battery to the chassis, then all the way over to the other side of the car through the chassis, then up to the trans. Just trying to rule ground out for certain.

Black soot is weak ignition or really rich fuel.
