i just swap a jdm itr motor in my 94 hatch, im having problems with vtec, it kicks in for 2 or 3 times but after that the check engine light some on and vtec dont work no more,even when its connected it loses power after 6,500rpm i conected all the vtec lines to the ecu. help!

 

u got the correct chip, i hope. double check. i believe its p73

you may need a better fuel pump, injectors....did u upgrade ur fuel system?

Is it a new or used engine, u may not be firing out all 4 cylinders, u can do a compression test to check this

There r a lot of things that u could have done wrone. I gave u a couple to start with. Do a search on engine swapping. Oh and I wouldn't drive that car till u fix the problem.

i got an obd1 p28 chipped ecu

 

i put an ls fuel pump and i have stock itr injectors

 

the ls fuel pump is probably not cutting it homie, get urself an itr fuel pump and u should see an improvement.

 

Try the Hybrid Forum. Not too many people in the ITR Forum need to swap ITR motors into their cars.

Some do....

 

i dont think its the fuel pump,im using a stock old single cam fuel pump with my itr engine in my eg.

 

It definitely not the fuel pump.. well at least its not because he doesnt have an ITR fuel pump.. Ive had about every motor in ym car ranging form a b16, LS-VTEC, and now a ITR and still have the same old 92 cx fuel pump..

as for your problem.... what code is you car throwing, you cant fix the problem if you dont know whats wrong...

 

check ur oil mine poped n and outta vtec 2 quarts low

 

what do u mean

Check your oil pressure. Maybe the pump is going bad.

 

what pump? oil pump?

Yes. Also check your oil pressure sending unit. Usually if it is bad the oil light will come on, but since it's a swap I would check it. Or it could be the vtec solenoid itself. Just have to trouble shoot.

This is 150% wrong!!!! you do not need a itr fuel pump and a bad fuel pump is not going to cause your vtec to fluctuate.

I would agree its probably something to do with oil... either low on oil, or your vtec preasure is faulty. Also check your vtec solinoid screen, make sure its not clogged.

 

its throwing check engine codes 17 and 21

 

did you check the codes, there is a code list on here so look it up u will need sum day and check ur oil like i said in the first place, what i mean is check ur oil, If you know how to!

 

almost positive it is an oil problem did you do anything yet or fix it?
