To make a long story short well, first i got a code 90 which was gas leak and after i fixed that i warmed up the car and the idle jumps around to 200 - 1000 - 500 basically it wasn't steady like how it was before so check the codes and got a code 71, 72, 73, 74 which is misfiring in cylinders 1, 2, 3, 4. what do i do now?? is the ecu messed up??? all the wiring is fine and plugs and caps is all in order because i tripple checked it

NEED SOME DEPREATE ADVICE IN HOW TO GO ABOUT SOLVING THIS PROBLEM...................................

 

ttt!

 

ttt

 

are u positive u have the correct wiring scematics on how the plug wires go on the dist?

 

are the plugs gapped correctly?
is the firing order correct?
plug wires good?
spark plugs good?
dizzy cap good?
Rotor good?

 

everything is good.................. the whole misfiring started when i had to check for a code when i got a code 90 then i accidently left the jumper wires in the service connector and thats when the new codes began........

 

hmm thats wierd i never heard of a code 90? any one else?

 

here is the code 90 its for a 1998 civic lx
