I have a b20b in my ef all the wiring is done rite by professionals and the vacuum lines are rite and the timing is dead on, Its obd0 using a pr4.. when I normally go with giving it normal amount of gas (lol hard to explain this bare with me!) only when its warmed up it hesitates between 1500 and 3k rpms, if i just get on it it doesnt really hesitate, keep in mind car has been sitting for a couple of months, ive changed my cap and rotor and spark plugs are alll NEW. Please help!

 

my brothers b20 in his integra did that and it ended up being his injectors.

 

okay, tomorrow Ill check that out.. thank you.

 

nvm, brainfart

 

If you clean or get new injectors and that doesnt work, try some new gas since you said it had been sitting for a couple months. And in any case replace your fuel filter if you havent done so.

 

What happens after 3000rpm? If it smoothes out it could be your TPS.

 

And if its at a idle it idles between 400 and 600 and after like a 30 secoinds to a min it will idle low then idle high and then idle again at 400 and 600rpms..

 

I unplugged my tps and it didnt die.. it kinda stayed the same idle and my check engine light came on... and when i turned the car off i couldnt start it with the tps unplugged.. so idk if its bad or good.. all my injectors are working.

 

I failed to mention that my iacv is missing the plate that should be on the bottom that suppose to have 2 hoses running to it, and one of the hoses thats suppose to run to it is plugged off... I just notice this.. any ideas if i should get a new iacv or find the plate for it and run the hoses..
