i disconnected my battery and unplugged my dizzy & vtec when i cleaned my engine bay. hooked everything back up and now it idles around 500 rpm and sounds like a wrx, i can barely take off in 1st gear & no check engine light . its a 97 ej8 sohc turbo

 

you sure you plugged your plug wires back into the right location/order?

friend of mine mixed his up & it sounded like a stock car.....

 

Actually did that to my car. My firing was off and my car sounded like a wrx.

 

lol mine sounds way nicer than a WRX when it idles @ 500RPM. But i got a built turbo D. It just sounds like that at low RPM. Its either TPS, IACV or FITV. Unless you adjusted the idle screw lol. I had mine adjsuted because it used to idle high as ***** on the auto ECU (i converted it to manual). On the P28 it idles low as ***** lol. Built D Rumble > Boxer Rumble.

 

sounds like you got water in your spark plug hole.

 

ya that could cause that. But thats def not the reason it happens for me lol.

 

this problem didnt start until i unplugged everything then plugged back up, i checked and rechecked everything is plugged up right i didnt remove the plug wires but i did forget to mention i unplugged the o2 sensor, could this be the problem ? it normally idled at 1000 rpm could the timing be off cause i unplugged the dizzy ? o2 sensor ? no CEL

 

no water in spark plug hole, i was cleaning with that orange cleaner and a rag not a water hose, i didnt spray it near my valve cover cause its powder coated and dont wanna mess up the finish

 

if u have no CEL then no. And unplugging the dizzy doesnt throw off your timing.

 

can anyone help ? still no luck

 

have you tried adjusting your idle screw?

 

this happened to me when i washed my motor and i then changed my plug wires and it quit...so idk this is just what i did when it happened to me

 

this, or i'll shoot my mother

 

my brothers d15b vtec had the same prob. He got his valves adjusted and it fixed the prob.

 

Map sensor?

 

have you tried unplugging sensors as the car is running to see? unplug them one at a time (and only keep one unplugged at a time).

 

im not gonna change my plug wires cause i just paid $60.00 for new ngk last month, i will try adjusting the idle screw and unplugging my sensors 2moro after work, im just stumped because there is no check engine light on and all fluids are good, it ran perfect before this.

 

ya it happened to my friend. HE washed his engine and then he started havin electrical problems. But he had no codes.

 

don't mess with that idle screw if it ran fine b4 you unplugged stuff then its deff not that. and your o2 sensor wouldn't do that if it was bad it would either throw a code or make it run rich depending on what is disabled in your tune. did you unplug things like your map sensor and tps for some reason?? they have the same plugs so if you mixed them up it would deff run like that. but it sounds to me like your firing order is messed up. or when you pulled your plug wires out of the head maybe the little clips in the wires that clip on to the spark plugs broke off. ive seen that a million times. usually it happens when there hot and you reaf on them to unplug them. cuz then it could just be running on 3 or less cylinders. id check that first then if that isn't it try the firing order. just don't go messing with **** you didn't mess with to begin with. hope that helps

 

here is some engine mods if it matters- d16y8 je pistons,eagle rods,skunk2 cam,skunk2 intake manifold,stock map sensor,ngk plug wires,ngk plugs(copper), zoom stage 4 clutch, aluminum flywheel, aem fuel rail,bigger injectors,aem pulleys,no a/c, short shifter, t3/t4 hybrid turbo, 38mm wastegate(10 psi spring)blow off valve, intercooler,cast iron turbo manifold,slim radiator fan,hasport mounts, its been tuned but needs a hondata, currently running 10 psi, 93 octane gas, synthetic oil

 

i never pulled my plug wires out they been in for a month now , this just happened 2 days ago, i didnt unplug map or tps sensor, but ill check everything over again 2moro. luckily i have another car to drive in the mean time. thanks for all the help

 

this may sound dumb but you said you unplugged your dizzy if i remember right so do you mean the wires that go from the harness to the dizzy or the plug wires on the cap.

 

ya well if you cleaned the engine with everything plugged in then maybe you got cleaner in the plug. i remember i got coolant in my VSS plug the other day any my **** was going crazy until i cleand it out.

 

i unplugged my dizzy at the harness not the plug wires to the dist. cap , i only unplugged everything because i was trying to re route some wiring to look cleaner because some of the wiring was looped around each other

 

hmm that's weird. and yo say its not throwing a code. does your cel come on when you first turn the key. maybe the cel is blown. cuz if you pulled to hard on the wires that go from the dizzy to that harness maybe you pulled or broke a wire like the cylinder position sensor wire or something like that cuz that would do that too. i mean im kinda going out on a limb with the cel being blown but it does happen. Ive also seen some that it didn't make the cel come on but once you put the jumper in to check the codes it threw codes but only with the jumper in. idk why they do that sometimes but Ive seen that happen too. try that and let e know and if its none of those ill try to think of something else. im sure its something simple.
