I swapped to a B16A1 a few weeks back, and I can't seem to get the car running right.
I sorted out my codes weeks back, and t ran decent after that.
But it was really sluggish on the bottom end, so I figured I'd advance the timing. I found that whatever the previous owner did, te put on the pulley wrong, because the timing marks are not even close to the mark. I'm talking multiple inches off.

Therefore I advanced by eyeballing it.
It seemed to help. Throttle response seemed a bit better, and it was generally faster from a full stop. Until 2 days later, when I started it up and drove off, after about a mile it started sputtering and backfiring. I went back home, and retarded the timing back to about where it used to be. The problem persists.
From a stop, my granny with her cane is faster. it sputters and backfires and reeks of rich mixture. Then...4K rpm, on the dot it drives off like nothing ever happened and runs like a champ.

WHAT THE ****? I don't get it at all! Tomorrow I'm switching my ignitor module to a D16 one to see if that fixes it. That's the only thing I can think off.
02 sensors are new. No codes, no CEL. Spark plugs+wires are new. Rotor is new. Dizzy cap is new. I checked and re-soldered a few of the dizzy wires 2 weeks ago.

Anyone have a clue?

 

I would fix your timing.
The timing belt may have slipped a tooth. Check that the woodruff key is in the crank pulley so the marks are proper.

Is the check engine light on?
Are you throwing any codes?

 

Like I said. No codes, no CEL.
But if the timing skipped a tooth... woundn't it run bad across the entire power range?
When cold it idles fine, and responds to the trottle normally. Only when it warms up a bit does it start to go apeshit.

 

I'm sure someone recognizes this problem.

If my cam timing would be off a tooth...the problems should persist higher up in the RPM range too right?
This seems electronic related. Almost software related :s

 

Bump.

I could use some help.

 

I would still check your engine to make sure it's all aligned. it can't hurt man.

only happens @ WOT?

 

no...WOT fixes the problem after 4000Rpm

 

I suggest you fix one thing at a time.
You know your crank pulley is WRONG - fix it. If ytou don't fix it you will never be able to time your ignition.

You may be having an ignition problem. The plugs/wires/or something coould be arcing. At higher RPM the arc may be going away. I've had it happen before so I wouldn't be suprised.

 

SOLVED! ;D
New dizzy...all symptoms have gone away.
Pulls a LOT harder now.
Timing marks line up nicely and everything.

This is one happy camper! Now to pick and pull the old dizzy apart. I'm gonna try my D16 module for the fun of it.

Thanx guys.

 

i had a similar problem that when i punched it hard in low rpm, it bogged.
i traced the problem to my coil, try that its easier to swap than ignitor
