Never heard it ping or noticed any thing unusual yesterday. But after getting home after a trip to town I parked it and the idle was getting lumpy. I adjust it to get it smoothed out some. It seemed ok. I just went out and start it up. It wont even stay runnig now. I wish i knew when it blew if it did. I will have to compression test it later today.



Well at least I made it through the summer. https://www.nopistons.com/forums/pub...IR#>/blush.png

You did better than me Dave...I had 2 engine's blow up during this summer https://www.nopistons.com/forums/pub...IR#>/blink.png This engine seems to be strong though...except for the exxon valdez I call my driveway https://www.nopistons.com/forums/pub...O_DIR#>/11.gif



Do a quick poorman's compression test. Check the plugs too. They might just be fouled https://www.nopistons.com/forums/pub...1047683329.gif

I am about to pull the plugs.

We shall see.

NOOOOOOOOO

god forbid https://www.nopistons.com/forums/pub..._DIR#>/sad.png

I knew ALL THREE TIMES I blew my motor...I could feel it... Especially the 2nd one. That one was the worst. It just gave out. https://www.nopistons.com/forums/pub...R#>/violin.gif

Did you check the obvious stuff? plugs, map sensor, etc...



Pull out the purple box and run the stock computer, see if it will idle then. My car did the exact same thing, and sounded like it was running on 1 rotor, I hooked up the stock computer and everything was good.

Plugs are definitely fouled.

Not sure why. Map sensor is connected.

Fuel pump relay is still good.

Notr sure . I gotta run to the doctors for an appointment but i am picking up some plugs and a compression tester while i am out.

Crossing my fingers.

I was going to race Sunday..

Oh, and I had my poor sick wife out there turning the car over for me.

I had the rear housing plugs both out and had her cranking it over.

It sounds like good strong puffs and is spitting out dark oily looking gas https://www.nopistons.com/forums/pub...1047683561.gif Not sure why the gas was so oily looking. I was just hoping not to see any metal shavings or flakes and I didnt.

So i am starting to think that maybe it isnt blown and I have something else going on.

Any thoughts?

I will be back with more later .

If the map sensor dies will it have the same symptoms?
