So I bought a zenki with rod knock and swapped in a junkyard engine over the weekend.

It runs pretty rough, bounces all about and when I checked codes get a 71 (general misfire).

I have looked over all the harness plugs and they all appear to be attached.

The newer engine didn't have a dizzy on it, so I just set it to tdc and lined it up to have the #1 plug wire pointed at by the dizzy. The fact that it started, means it must in the neighborhood. I threw a timing light on it and moved it about on the timing marks, till it got as smooth as it gets.

Put new plugs in it(the old ones looked fine).

I also kept the old throttle body as it has one more plug on it than the newer one( mine is auto the other was manual).

I was hoping the diagnostic lights would tell me something a bit less vgue than this.

Any suggestions?

 

i know it sounds dumb, but double check your firing order....
the ka will run, hell, it will even drive with the wrong firing order.
I have personally driven a 240 with the firing order messed up so only two cylinders were firing properly.

 

and make sure the new distrubutor you but in has all its teeth.

 

The dizzy was just the one off the old engine which ran fine. I pulled it with wires, so they didnt get mixed up.
thanx for replies.

 

CLose, but no cigar. I pulled the plug wires one at a time and #4 is not running. Listened to the injectors, no click-click on #4. Guess I will pull the old one and try it in that hole.

 

tkae two wires and click the battery straight to the injector. dont hol dit on the injector, just click it until it frees up. you can even ta it with an extention to free it up inside

 

Ahh, good suggestion, but I already pulled the rail and injectors from the old engine and swapped them. Kind of a pain, but I couldn't get the injector off the new engine rail, so went with my favorite solution, Brute Force.
Runs fine now.

Thanx for the replies

 

congrats.
brute force, its amazing when that works huh
have fun
