I am gonna kick the shit out of this thing. I replaced the o2 sensors today and all seemed well on the ride to work. On the ride back, it started doing it again at sustained highway cruising speeds. Additionally, my factory tach has always been jumpy around 4k but now it is everywhere. The VAFC does not show any jumps like the factory tach does so I am stumped. The only thing left that I haven't replaced is the distrubitor. The car now reads a little on the lean side and NEVER goes rich unless it is from a cold start. 12 MPG is not fun anymore.

 

Replaced the ignitor today (that expensive thingie inside the distributor) and the tach issue went away. Now it seems fine and dandy until it hits 7k in second gear. It feels like it hits a damn wall. Don't ask me why it does not do this in first or third.

My parts tally:
ignitor
cap/rotor
o2 sensors
plugs
wires

Could it be my main relay about to take a dump? I feel like torching this car.

 

I had similar problems on my ex-girl fiends Civic. I replaced all kinds of shit. And then a friend of mine just happened to have the same thing to his Accord. And he finally took it to a shop after replacing the wires, plugs, o2 sensor, distributor etc. And it turned out to be the coolant temp sensor on the side of the head. It was like a 60 dollar sensor. But you'd be surprised how that thing will make your car run like a POS. But her car would bog down really bad as well, But that fixed it. Hopefully that helps if you continue to have that problem.

 

By the way hers started out as intermittent problem as well. The way describe it sounds exactly the way her problem started out. I pretty sure it's going to turn out to be the coolant temp sensor. I bought her car for a service station that had a mechanics lean on the car and it had been sitting there for a little under a year.

 

try the map sensor this sounds liek a issue i had

 

Why not, on Monday I'll pick up both of those damn sensors. At least they will be new. Ugh.

 

you still got the crappie stock crx fuel pump on there when i had my c5 in my crx it did that after like 20mins stright driving it would run funny it was cause of the crappie stock fuel pump so i bought a 94Gsr pump and it ran like water so smooth and even nicer on the pedal

 

make sure all of your ground wires are connected securely ive seen all these problems describe because of lose or disconnected ground wires just a thought before you go spend alot more money on sensors

 

bad gas maybe

 

That seems like a good idea, I was wondering how well the stock pumps would hold up. It seems to be running lean now anyway. It has an AEM fuel rail and a Skunk 2 manifold on it which probably don't help things out air/fuel wise. My plugs are about ghost white and I havent been beating on it anymore.

I'll check the grounds on it to be sure.

I knew it had bad gas in it for the first 1/8th of a tank, but it is all gone over 2 weeks ago. I try to run Amoco ultimate in it until I find this issue.
