Message	hi all, I have a 1993 NA, totally stock, that has a "newer" engine swapped in in 2003. It runs fine after a couple of seconds but when I first start it it will start like normal and rev up to about 2k rpms, then it will seemingly bogg down to about 500 rpms, and then get back up to about 1500 rpm while it warms up. It doesn't happen again throughout the day, even if the engine is cold. Only in the mornings. I am putting 91 octane into it, only from big name gas stations (bp, shell) so I don't think there is any ethanol in it (i live in nebraska). Any idea what it could be? I'm pretty sure the injectors are the newer style because the paperwork I got with the car had the dealer replacing the whole wiring harness when they swapped the engine. Thanks in advance guys
