I am posting for a freind, I am working on his car now.
Its a 97 cl with a OBD1 H22 . He is running the h22 ecu and a jumper harness to convert to obd1 .
The problem is that teh car will run and everything but when you hit 2000 rpms its like hitting a rev limiter.
Has anyone ever ran into this .
The car is throwing idle air , tps, and a colant sensor.
Any help would be good.
Thank you

 

try adjusting the tps sensor up and down. im pretty sure that if the tps is bad it makes the iac think its bad, which gets info from the coolant sensor.

 

uhhhh. no?

first off, what ecu are you running? make sure the tps is not busted, unplug it and run the car, it should run ok with the base maps in the ecu. also make sure the map sensor and tps sensor wires arent swapped. they look very similar. also make sure the a6-a11 swap was done on the conversion harness. very important. you will be much better off searching for help over on Honda-tech.com . they are assholes over there but they know what they are doin. Search before you post and you will be ok. oh and from what wilp99 said..if the engine is a jdm you can use a star bit and a pair of vice-grips to adjust the tps but if its a usa you are going to hate life. They are rivited on due to emissions. You will have to remove the TB and grind or drill the rivets out. good luck.

 

Also what jumper harness are you using? I had to goto SKUNK2 because the one I used was wired incorrectly and made problems for me worse in the long run.

 

yeah a lot of them are junk unfortunately.

 

The plug on the tps is green I think . ?
Its a jdm honda parts harness I belive. It says on it I will look.
I can also try swaping those clips around.
Oh yeah and teh ecu is a p13.
Thank you

 

The car is also running open header. I found out that the kid didnt even put his o2 sensors back in. So I am sure that is why its in safe mode.
I will get the o2 sensor and exhaust on and see what happens.
