What's up Honda-Tech I was wondering if someone could tell me a solution to my JDM B20 swap not reving past 3k RPM and then when it hit that mark it bogs down to less the one makes a loud exploding sound in the intake manifold/throttle body almost as if its sucking to much air when i rev it keep in mind no check engine lights are on and im running a base map on my Hondata S300 for a b20 so i ruled out computer issues checked timing thats good changed distributor fixed vacuum leaks but if anyone has a correct diagram just in case that would be fine ive done everything I've done my research numerous times now im asking for direct help as I need this car for college now to make it easier thank you

That's just...painful. Can you at least try to use some punctuation, and give us something legible to read? Is the CEL on? Does it work? Was this swap running properly and then started acting up, or has it not run correctly since you swapped it?

 

You might have the TPS and the MAF sensor connectors swapped

 

Sounds to me like your ignition control module has gone bad. It's located in the dizzy and you can remove it, take it to a local parts store, and have them test it. Make sure the test it 3 or more times in a row to get it nice and warm. Replacing usually cost around 80 bucks
