[aaronscomp]

Ok i bought my swap from a kid that really didn't no wat he was doing i got it running it idle strong but wen i give it gas it pops and hesitates ive been messing with the timing but still does it i put it to 15 dg tdc it looks like he wire a sohc maf up with no safc would it cause it to hesitate and pop without a safc to correct it. Any help would be greatly appreciated

where and when does it "pop and hesitate"

what does it do at idle?

are you getting proper vac?

how is your mechanical timing looking?

back fire?

have you pulled your plugs and checked them?

Ok it holds a really strong idle, and by mechanical timing do you mean cams and belt right? if so its on right all the marks lined up correctly wen changing the belt. I'm not sure about the vac though, its not really like a back fire i could get a video if it would help just as soon as i give it gas it starts to pop almost like detonation if u no what that sounds like it does it gets a lot worse when you actually drive it i haven't really touched the gas at all im trying to avoid hurting it. As far as the plugs go i actually just replaced them today to get that out of the way.

could be your ignitor, could be a grounding issue, could be a coil.........

a video would help.

ok ill try to get one tomorrow or something ill try igniter chips it has a sr20det one on there if that matters also

Ok i haven't really be messing with it much been waiting for my sr turbo i installed made a new oil feed line so it would stop leaking the leak is fixed now. Ok here the prob now i don't think its the maf nor the igniter chip. First off i took the thermostat out because it wasn't opening so now it runs really cold. But it seems if i let it set and idle with the e fans off and let it warm up it has good throttle response and pull's hard also but after like 3 min or so it starts to cut out. Could it be the no thermostat ill try to get a video soon if i can find my camera. Its really cold outside right now also so as soon as you drive it with fans off or on the temp goes all the way down.

if the breaking down is around 2500rpm then there is a problem with the AFM signal and the ECU is in limp mode.

Well everything seems to be running good now put a new thermostat in it and it doesn't cut out anymore i thought that was weird hopefully the ca18det does me good
