Alright, Car was running weird so i went to Advanced Auto, Grabbed the OBD2 scanner and got a cylinder 1 through 4 misfire and a random/multiple misfire. I just changed the plugs and wires (both NGK and correct plugs gapped correctly also.

I changed the plugs before, Cleared the codes and they came up again.

I wanted to get some input before i start doing things i don't need to.

Any help would be awesome and appreciated! The faster the response the better

 

Any ideas?

 

if all 4 are you should try replacing your cap and rotor. have they been changed before? how many miles on the car?

Changed the rotor, It's new.. MSD. Miles are 156K but that shouldn't matter to much?

 

change the cap to. if it hasnt been done it deffinatly needs it. if it doesnt help then look for a new distributor

Changing the whole distributor tomorrow so we'll see.

Any other ideas people?

 

let us know if it helps. good luck!

 

Coil or Ignitor.......most likely the coil

 

Still getting the misfire after replaceing the WHOLE distributor.

I ran the scanner and got the same codes after resetting the ECU and clearing the codes.

Soo.. Changed dizzy/wires/plugs/fuel filter/Checked timing..

I'm guessing to check the Injectors next? I have read and heard they can cause a misfire also, And after doing the things i've done so far it only seems right to change those next, Right? So last night i bought some ITR injectors. Now i just need to put them in.

Any other ideas come to anyones mind on what could be causing this misfire if the injectors don't work? Fuel pump?

 

Ideas?

 

I get some new O-Rings today so the injectors go in.

 

it may be the injectors but you need the check the coil, i also have msd and my car started doing this and the last thing i checked was the coil and it turns out it was

i checked it with a voltmeter and everything, i just decided to pull the one off of my buddys car and try it on mine, and it worked, so i bought a new one

my advice is trash the msd, its caused me nothing but problems

in your list of things you checked you didnt list the coil, if you did check the coil, it may be the injectors

 

Already checked the coil, Hints the whole "changed the dizzy" deal. And i don't have the full MSD set-up, JUST the Rotor. Which is a replacement for OEM.

 

Hmm, Still gettin it. Maybe an ECU issue?
