1992 Civic VX D15z1
When cold everything is great.
once the car warms up, I can't drive in 3-5 under 3k rpm's without the car sputtering. You can either accelerate or slow down, but it won't take hold speed under 3k rpm's. Yes this is the VTEC-E with the 5 wire O2 sensor. |

easy solution....YANK that motor out.

Re: 1992 Civic VX D15z1
any check engine lights?
Could be spark related like a distributor cap or plugs and wires. |
Re: 1992 Civic VX D15z1
sounds to me like you're just going into lean burn and confusing it with a problem. i could be completely wrong but my 92 vx is similar to what you describe.

Re: 1992 Civic VX D15z1
there are not enough Z1's on the road anymore, please let it be a survivor.
suspicions (in this order due to price) plugs/wires distributor cap/rotor distributor bearing going bad O2 sensor close to dead |
Re: 1992 Civic VX D15z1
Generally misfiring at low rpm and heavy throttle is due to weak sparks. It gets worse when the engine is warmed up and the ECU switches over to closed loop mode, which leans out the mixture. The oxygen sensor can also cause runnability problems on these even without it throwing a code.

Agreed. We need more survivor cars and fewer project cars

I think he was referring to complete VX cars, not just the engine.

Yes, I realize this. Only, I was expressing the compromise I took in order keep a perfectly working D15Z1 alive outside of its unsalvageable original home (prematurely rusted due to neglect by the P.O.).
I also miss the look on parts people's faces when you have to explain that your civic is not one of the normal ones on their list. (back in the late 90s the VX was only listed in a few aftermarket parts store's listings, this made things suck at times) |
Re: 1992 Civic VX D15z1
Yeah I've unfortunately sent a couple of them on their way but my VX didn't have an engine when I bought it and my CX didn't either. If I had the space I'd do my part to save what I could as well.
