I just got a new 87 GXL and it runs near perfect completely stock, except it wont let me get past 4 grand. soon as i hit 4 thousand it sputters and sputters and completely stops accelerating. any ideas on wtf is going on?

i think it could be my secondary injectors...

Those come on at 3800 rpms.

Injectors, tps, or fuel filter.

yea check your fuel injectors (secondarys) make sure the clips are good... there should be a metal on everyone at the end... i know this cause same exact thing happened to me just i felt liek an idiot cause i drove under 4k and a pick up pulled up and was lookina nd tried to take off and i downshifted and ity wouldnt go nowhere pass 4k

3800 that means just enough where you can tell at 4000 if they dont come on thats why i suspected them

I know what you mean, my 7 is doing the exact same thing, though I am not suppose to take mine over 4k cause its not fully broken in, but the fact is mine isnt either

according to RETED, it would be because your engine is cold

according to anyone with ANY intelligence, it is your 3800rpm hesitation

i trust people with intelligence
