ok so i have a 1990 CRX SI that i put a d16z6 head and intake manifold on with 89 integra high dome pistons skunk 2 cam gear and MLS head gasket all 2gether and installed i started the car it runs for about a minute then the RPMS go2 3k then go down then back up hten dies or it goes 2 3k then just dies and the engine light turns on i cant get the ECU 2 throw me a code it just keeps blinking 5 times then stopping over and over again. is this because i do not have a p28 ecu or could this be somthing else? i still have the intake mani from my crx im going 2 try and install that one instead of the z6 one and see what happens. if you have done this swap before please hit me up this is my first time doin a engine swap i live in Glen Ellyn IL if you live in the area and have done this swap before i would greatly appreciate your help i have been working on this car for a year now and i just wanna get it out already lol if u wanna get ahold of me out side of hondatech email me at djdfuzzion@yahoo.com

 

Code 5 is MAP sensor. That is why your car is revving to 3k and then dying. MAP sensor is on the intake manifold if you are using the OBD1 map sensor or the obd0 one is on the firewall. Make sure there are no holes in the hose that goes to the throttle body.

 

is that the sensor behind the throttle body or is it the one on top of the throttle body of the z6? the stock crx intake mani only has 1 so im guessin on the z6 1 is throttle body pos and the other is map

 

On the stock CRX its mounted to the firewall its the 3 wire sensor. If your using the Z6 throttle body its mounted on top of it.

 

thanks im pretty sure i got it still throwin a code for it though i think imma change my throttle body if it doesnt change after i change the ecu i just bought the p28 ecu gotta find a coolant leak and ill b in business after i wire my v tec

 

so now i have a new problem i didnt know about when i press the clutch in and give it gas wen it gets past 3k it bogs out and the engine makes a hissing noise and even with the map sensor plugged in it still spit the code for it so im thinkin i need a new one but it does run without dieing until i push in the clutch and give it gas then it dies what could this b

 

the map and tps plug are identical make sure you haven't got them swapped around
