I bought a 92 civic cx that had a d15b7 out of a del sol in it. I found out it has an automatic ecu in it. The car seems to like miss if i'm driving it easy. If I ease the gas down it does this till i reach about half throttle then kind of just takes off. Also, it doesn't matter if i go WOT or just ease on the gas, but when it hits about 4k it gets a ton of power like it's hitting VTEC. But obviously this car doesn't have VTEC. So what could this be? Maybe the timing is off?

I just replaced the plugs/wires and fuel filter thinking that might of been the problem. You don't think the automatic ECU would do that would you?

 

I forgot to mention it seems like it really only does this after the car is warmed up. When it's cold it drives fine.

 

When you pull CEL codes from the ECU, are any retrieved besides automatic transmission code 19?

 

Nope just code 19.

 

anyone?
