Help spark plugs shot! Options

[bdog_v]

Hello my 94 GT celica has been sitting for about 6 months stored and today I started it up changed oil and it ran fine. Later today I went to start it and it fired up and then died after about a minute. To my surprise the spark plugs are looking shot and they only have maybe 2,000 miles on them. I have champion spark plugs and they look as if the center has worn away to the point that the gap is all off and I need new plugs so my question is

-What spark plugs last the longest and give good mileage? What should I buy...




-Also I run a straight through exhaust with a header and a magnaflow muffler ,plus a cold air intake. Is it possible I was running too lean or hot those 2,000 miles and wore away the center electrode. 3 of the plugs are redish brown and 1 is grayish white on the insulated porcelain......

Thanks, Brandon

I highly doubt your injectors would all crap out at the same time. if one injector went out (which is more likely then all of them going out) you would have a misfire in one cylinder. your engine would be all rough and shaky and the car would be super slow. I would check that vacuum line from the MAP sensor and see if it's cracked or their is a hole in it or something.

I don't have a pic of it right now, but it's just this little (maybe an inch long?) plastic box thing. From what I know they don't usually crap out. if you can, maybe find one from another celica you could just swap in (takes only a minute to swap) and see if that fixes it.

Oh yeah, it stands for Manifold Absolute Pressure sensor (I'm pretty sure) and it tells your ECU how much air is going into your engine in order for your ECU to spit out the correct amount of fuel to get the right AFR (air/fuel ratio)
