Did you check the head light fluid? jk jk jk I personally would look for a vacuum leak. Are you running an after market computer or have you made any modifications to your ECU?

Ha ha lol ya all the fuses are good. theres also no vacuum leaks that i can tell . Im running the stock p75 ecu with a rywire harness for the tcm . I also have a p06 ecu that is modified and chiped but it runs the same no madder what ecu im useing

Is the check engine light on? What kind of ecu harness are you using, it should just be plug and play?

I had a 90 integra that I swapped a motor with a bad head gasket and some bad rings for the exact same and it had a very similar issue even though the it was the same motors and it turned out to be a vacuum leak to the intake that I would have never found if a buddy had not pointed it out. I would check it over and listen just to be safe otherwise I have no idea but good luck ether way.

No cel and ya thats y ended up getting rywire obd1 to obd1 converson harness for the ecu to plug into the tcu so i didn't have to wire thoes two things but still had to connect to trans and shifter but that was easy

Found out it was a sprk plug now idles a lot better but still have a nother problem if i give it gas really slowly it will run if stomp on it it will bog down and die0

If it was a sparkplug I'm going to guess you haven't done any kind of tune up.

i would start by getting a new engine harness. that one looks hideous and may be the problem.

b18b1Ej

No its not the nicest but it does the job because it was on my 1.6 dohc turbo set up and was working fine

b18b1Ej

It just the injector wire that look bad but all have good conection its because there not stock i guess i could make them look better though

Check and adjust your TPS if its out of adjustment. Does your check engine light work?

b18b1Ej
