Usually the 2500 rpm issue is indicative of a wet or bad TPS. You may want to try hybridz.org, zcar.com, or zdriver.com for some assistance, rather than here. My '82 ZX would do that every time I cleaned the engine bay, I'd have to take the plugs off the TPS & MAFS & spray them out with electrical cleaner spray & wait for them to dry out. Another possibility is your fuel pump might be going out...
