adjust down your idle to 700-750 then check your timing and your problmes should be solved unless you have a vacume leak. Also you should of changed your pulgs if you didnt when you put the new motor in. ---

Yea, it definitley sounds like your ignition timing is out, and I pretty much agree with everything else jjm\_240sx said. You might also want to clean out your IAC if your running rich & idling high, those are both symptoms of a sticking IAC valve. If you want to check for a vaccum leak and you have a guage it should read between 22 - 30 hg of vaccum. Good luck man P.S. If you dont have a guage for vaccum & think you have a leak there are plenty of other ways to check for it without a guage. ---

> [@240 ville](#): > > ok thanks for all the help and if someone could help me out with number 3 that would be great well for number three it could result in not enough spark or not enough gas… Soo theres a few issues like a fuel filter, fuel pump or wires, coil… A few factors but theres ways to check but a fuel filter is a quick cheap fix and you should try that if you havent changed it before. But thats my opinion. Before i had an issue where it wouldnt pass 4,000 rpm and it was because i only had 3 outa 4 cylinders working… one of the wires technically exploded on me lol soo id check with your wires/plugs/fuel filter… mayb your injectors… who knows :?: ---

fuel pump…timing mabey…but tell me this… was the newer motor that you put in idling just fine…becasue if it iwas then dont go screwing with the idle adjustment…becasue thats a half ass way of covering up the problem… ---
