i work hard for this car, try to pay this thing off. im really out of time plus i dont have a garage. i just order new intake filter,coupler and all T blot clamps. hopefuly it will solve the problem.......could it be other things such as fuel pump? 02 sensor??

You could have just cleaned the filter and saved . . .

Could be a leak somewhere or your DP may throw a code. Your fuel pump should be fine. Maybe your SRI needs some sort of air straightener?? You could also need a tune. Frankly if you install a DP you should be willing to invest in a tune or gauges so you can see whats going on.

I get the same code you do but its because of my AP tune. Im getting custom tuned so its only temporary.

+1000. Then reinstall intake if restore to stock solved problem. Work on one issue at a time, isolating the mod. Consider staying with stock bpv.

put everything back into stock except dp/rp, it feels alot better, hopefully it will solve my problem.....

P2187 could also be associated with a high pressure fuel pump failure to reach proper flow and pressure at the idle speed.

a faulty fuel pump with cause fuel cut?

Most likely cause of a lean at idle CEL is a post MAF leak in my experience. Just some food for thought...
