Ok the car has been sitting for 2 months(WINTER) it was warm today so I put the Battery in it and started it and took it out of the garage. After it warmed up i gave it a shot of gas and it back fired out of the intake. It did it 3-4 times then stopped. Is it just because the computer was calibraing after sitting with the battery out or something else?

Thanks For The Help

 

Its possible I guess, but if it quit I wouldn't worry about it too much.

 

No other thoughts on this? I was hoping for more.

 

More? Ok, I'll try.

Misfire due to moisture causing crossfire between adjacent, marginal plug wires? Dried up and backfire went away with heat.

Sticky intake valve not fully closing, maybe valve seal hanging up on gummy valvestem until it cleaned itself off again?

Really strong ants crawled into your opti and had a hellava good ferris wheel ride until they got flung off?

 

The plug wires is what I was thinking.I have a brand new set and Opti MSD rotor and cap to put on this spring.Hopefully that will stop it. As for the valves there fine just instaled new springs and the 1.6 rockers and rubbers.
As for the ants it's to bam Cold up here for the ants to move let alone crawl into my Opti!!LOL


Thanks for the input it's what I thought it was!!!!!

 

Could have a vacuum leak.

 

I did fail at my first attempt to fix the intake oil leak!!!! dident wrap the exaust tub with header wrap! The artical i read said i probally would fail, now it just leaks a little. but I will also try to fix it again this winter.
Thanks
