I just replaced my injectors (87 cherokee ) now its running rough. I used a lube to install them , could I have plugged them. Or I used a clamp to press them in (was that bad?)

 

LITTLE BALL, LONG GREEN, TEE YOUR WHITE BALL...................................

Light Blue, Light Green, , Tan, Yellow, White, then Black are the injector wire color codes I think. Maybe that could be it.
If you know the pair in the middle is right, you only need to check one on each end.

 

Did you reset the ECU?

 

Make sure they sit tight and hopefully you did not connect the wrong hardness.
Did you label the hardness prior to removal?

I don't believe the renix needs to be reset. OP, make double double sure that vac line to the MAP made it through the process without even the slightest crack. If it doesn't get good vacuum it will ruin your day!

 

Renix doesn't need to be reset.

Good advice on the MAP sensor line.

Double check the injector wiring.

 

wasn't sure if the renix needed a reset or not. x3 on the injector wiring. The two that get mixed most often are the 2 at the back of the engine so make sure to check those.

 

Thanks I found that wires were correct so by elimination I found #5 was faulty by the way what type dog is that ? I have a catahoula looks like that.

 

That MAP tube has no tiny crack and you can feel vacuum at the end when you pull it from the map. Well that's good. Did connecting the wires to #5 injector fix it?

Oh...just a gentle friendly loving old Lab. Unless he sees another dog with *****, then he's a ferocious over sized Japanese fighting dog, (his Sharpy 1/2 comes out). Steve was the "stealth pooper". Did not leave a pile in 14 years. No ****.
