pm s2000junky or moddiction.

they both had similar issues. and it turned out to be that they got the wrong fuel pump and one went bad after like 4k miles of use. there is a walbro 255 and a walbro 255hp pump. the hp is required. you may have the wrong walbro or a broken walbro.

also, did you get this kit new or used?

 

My guess is your car doesn't like these plugs. These are non resistor plugs and can cause interference/misfires to different degrees. I had issues with my radar detector with these plugs. You need to stick with an OEM rated resistor plug. A popular choice at one heat range colder is the NGK (2668 stock number) BRK8ix - I think I'm missing a letter here but you just need the stock number for reference when ordering. These are more expensive, but a much better plug, i've got over 40k miles on mine and still in great shape. This is an easy thing to try first with trouble shooting your issue. Try this and report back.

Also to note, do not gap these plugs, install them as is out of the box. They are pre gaped to 0.32-33 which is good.

 

i'll give these plugs a shot. Also, I bought the kit used, however I bought the fuel pump new. I am going to go check my invoices, and make sure I have the right fuel pump

 

yeah, plugs or pump. its gotta be one of the 2.

thanks for replying junky, i remembered your thread and thought you could be of some assistance. :-)

 

NGK Iridium IX Spark Plug BKR8EIX #2668

I too run these (with my SOS Base kit) and as as junky states, leave the gap as-is. However, I believe the gap on my set for these plugs was 0.30.
