Hello everyone. My car has bene plagued by CEL codes from a stock swap(d16y8). Okay, just installed a knock sensor to get rid of my last code. I reset the ecu and let the car warm up. I go for a drive and immeditaetly the car bogs. Let me describe: I give it gas and the idle drops slowly even while pressing ont he gas pedal, then BAm all of a sudden and half throttle it'll act normal and start moving. Kinda like a late response in throttle. It does this to the point where I have to put in the clutch rev it up then go. Then, it'll bog some more. Eventually after 2-3 minutes it'll throw a code. I go to check the code and nothing! The CEL just blinks, every 3 seconds forever. any ideas? PS: this did this before the knock sensor as well. majorly bummed

EDIT: forgot to mention, once the cel comes on and it goes into safe mode, car drives fine!

long blink or short blink? sounds like code 1 or 10. How is your fuel pressure?

Punker1234

long blink, so maybe code 10? also check that i mentioned once in safe mode it runs fine

Punker1234

ALSO, if it is code 10, yes my intake air temp is unpugged cus fo my cold air intake, but why the hell would that throw a code? and i don't think that woudl cause the boggy action going on

IHateJDM

10 is IAT, which shouldn't make your car run like that. Did you replace the timing belt during the swap? If so, are you sure its not off a tooth?

Punker1234

um, didn't do the swap myself. could that most likely be it?

well that happen to me when i swap out my intake manifold and i found out it was because i plug the tps into the map sensor so try swaping them around

Punker1234

my buddy said the same thing but the sensors won't even reach to switch, think my buddy looked the harness around the wrong way haha. also if they were switched, wouldn't it throw the codes for the map and tps sensor? also. wel i knwo that my map sensor plug runs right off my air intake temp. sensor, so thats right?

Is this on a obd2 car? Could be your plug wires too, my eg had the same bogging problems and it turned out to the plug wires.

very possible, and it won't take long to check.

this is gonna sound dumb but u mean timing on dizzy or timing belt? i can't chekc the timing belt don't have the little tool or whatever

timing belt, but if you advance or retard your distributor and the motor runs better or worse, thats a pretty good sign that the belt is off a tooth. All you need to do to check the belt is to take off the plastic timing belt covers, and line up the dot on the crank with the mark on the block (should be straight up), then take the valve cover off so you can make sure the arrow on the cam gear is pointing straight up.

Try swapping your map and tps first though, it won't hurt anything and it takes less time.

kk. will give it a go but do u know which ones are connected in terms of map sensor and air intake? arn't they right next to eachtoerh on the harness? and the tps is farther back

Punker1234

kk switched sensors. the mpa and the one behind the tb and no good. drove worse, couldn't get it passed 2,000 rpm. soo the only thign left could be the timing?

that's what I figured, but as a rule of thumb, always check the easy stuff first. timing isn't the only possibility, but IMO (from experience) its the most likely.

cool cool any other thigns i should look out for? i mean ti's just strange. also, why is my air intake cel going off? i had a cold air intake before and no cel code...

I don't know, but I doubt its related. I drove with an IAT cel for about 4 months before, and I didn't notice any changes in how the car drove. Right now my IAT is broken again, but my chipped ecu isn't looking for it anymore, so no cel. was that y8 ever turbo (from whoever you bought it from)? turbos have a tendency to burn up iat's.

Punker1234

coulda been. he said it wans't but you never know. So if the sensor is broken it will throw a code? or just if it's unplugged?

Punker1234

buddy told me line on cam should be aligned with the block, meaning horiztonal, but u said straight up. anyone else? haha

Punker1234

heya, checked the timing and it seems okay to me. It's the white line not the red line right? My buddy said it could be the TPS going bad? any other ideas guys? please car needs to be smogged in 7 days!

kyden

does it blink when you drive? thats an indication of a misfire. try checking the timing with a timing light.

Punker1234

it doens't blink when driving, only when I try and check the codes. it just blinks about every 10 seconds. but when i reset the ecu, it doens't have one until like 3 minutes later. SO im thinking the code thats in the euc isn't really the air intake temp or it would go off right away yea?

timing looks good. the white line is tdc. the red line is used with a timing light to set your ignition timing.

Punker1234

ahhh sweet. so anymore ideas? maybe i shouldtake int he ecu to gett he code checked so I know for sure? any place that checks for free?
