heres what hes emailed me.

I am not experienced with hondas. A friend of mine has a 1999 Honda Prelude type SH. Apparently that stands for super handling, but I say the car is super gay. Recently, the car started getting all sorts of codes. P0300 (general misfire) P0301 (cyl 1 misfire) P0302 (cyl 2 misfire) P0303 (cyl 3 misfire) P0304 (cyl 4 misfire) and P1399 (no fuckin idea). The P1399 was pending when I scanned it today, and all the others were active. The car has a funky idle. Kinda does feel like it has a misfire. When you hold the gas pedal down slightly to raise the RPMS up to about 1,500, it runs perfectly. When driving the car around, it runs perfectly. When you come to a stop light or stop sign, then it gets the funky idle. It also has a rough starting issue. Cranks over longer then normal.

So I unhooked the battery and let it sit awhile. I was first going to locate and clean the MAF sensor, only to find it doesn't have one. I took off the distributor cap only to find its spotless inside there, along with the rotor. The wires are brand new along with the spark plugs (NGK's).

The owner of the car has a lot of dumbass friends that keep having her throw random ass parts at the car and nothing they recommended worked. The car DID need a tuneup, so I can agree with the plugs/wires/cap/rotor, but some of her friends said to try o2 sensors.... (wtf? it doesnt have a lean/rich issue). The thing that throws me off is aside from the CEL, there is another warning light illuminated on the dash that says "ATTS". I googled it and it stands for Active Torque Transfer System. I have no idea what it is other then it actively transfers the torque, but I don't see why the car would get a misfire then suddenly have a malfunction with a torque transfer system. My take on all this is the car may need at minimum a fuel filter ($25 bucks) and MAYBE a fuel pump. Seems like its starving for fuel with the long cranking on startup. I don't have a fuel psi gauge to test line pressure to confirm my theory.

After hooking the battery back up, the car did run better. The CEL and ATTS light was off and it seemed to be idling pretty decent, but that can still change a day from now. What do you guys recommend? Anyone know Hondas?

BTW the car is 100% stock right down to the air filter, has about 130k miles and other then this crap the car is in great shape. :confused

It sounds like the misfire shit is either a distributor being WAY off, installed backwarsds, or all the wires are installed on the wrong cylinders. You should ahve your frined take the car to a professional and have them simply unhook all the spark plugs and wires, check them, and re install them. It most liekly is the wires being switched up. Keep us updated dude

If its a 1999 i doubt that the distributor "is off" because the ecu controls this. at least i know when i redid my motor adjusting the distributor did nothing (i think this is because of the obd2 ecu it determines when to fire automatically). secondly to test if your spark plug wires are shot just get a multimeter and test the continuity between them (25 Kohms max), this is a common problem. Iv been having some idle issues as well so what you should try is a couple things. first clean out your IAVC, bleed your coolent, clean your FIC valve and check your pcv valve for starters. check the links below:

hope this help even a bit and gets you goin.
good luck

ps i included a diagram (attached) of the order for your plug wires to be in (in response to mattliston's post). remember number one cylinder is by your cam gears and then number two is next, then three and four is by your distributor side

If the ecu controlled the spark, you would not have a distributor. you would have what are called coilapcks, which are almost always better then disty's


Plus he said the cap and rotor looked good.

Either way, Im sure its the ignition wires that need to be looked at. never hurts to make sure lol

And your diagram is correct, all of hondas 4 cylinder engines fire 1-3-4-2
