92 Accord rough idle, poor exceleration.
Just swapped my blown engine with a low mile replacement on my 92' accord that I bought with a badly blown HG and almost seized motor. Just the long block was replaced, and everything on the old engine was working great prior to swapping it onto the new engine. Confirmed good compression in all holes after transfer.
Engine starts up initially when cold, and idles smooth. After a couple minutes, idle progressively get worse, & starts to stutter and hesitate. When held at high RPMs, it seems to clear slightly but RPM's on the tach show wild fluctuations that are not consistent with
The actual RPM's from the engine. When driven, will hardly stay running in drive or reverse when at a stop. I have really spent a lot on this car with this engine replacement, and am sweating having to bring it to a shop for diagnosis. Double checked no air leaks, cracked hoses, etc.
Trying to find the best start. Valve timing? Ignition system? (was working fine before swap)
New engine was supposedly just taken from a low mileage wreck, and was running perfectly, but I guess that doesn't guarantee anything...
Any help would be greatly appreciated.
