hey guys i have a problem with my ek i did a obd 1 gsr swap with a 97 ex harness and why is my car idling 2000 rpm to 3100rpm and so i switch the map around then it stop idling but my rpm is at 1200 and then when you rev it it cut off at 4500rpm a friend did a check engine flash and got a 5 flash what is it

 

MAP sensor

 

will there be a different if i use a Ls map sensor cause i try it and it did the same thing

 

come on guys i really need help

 

I put a temporary d16y7 into my ek project. Basically a OBD1 to a OBD2 car. At first my idle wasn't so great either. After F'ing up the IACV and a week of work I found that just properly resetting the car got it idling fine. Also understanding that the IACV on my engine is warmed by the antifreeze so it doesn't go smooth till the engine warms up.

 

can you rev it past 4500rpm

 

i switch it with a b18b and it still did the same

 

try switching the map and tps plugs with each other, you may just have them backwards which would explain the rough idle and the safe mode low tach

 

yes i switch the tps and map around and the rpm came down to 1200rpm but i cant rev it best 4500rpm

 

are you sure that you have enough coolant? did you let it run up to temperature with the cap off to get out any air in the coolant lines, helps to squeeze the bottom radiator line as well, all the vacuum lines correct, if you unplug the iacv can you rev the past 4500?

 

i havent try running it until it run up to temperature with the cap off yet but i bleed my coolent one time got some some bubble out but still did the same. but i havent try with the unpluging the iacv but i will try it thank for the up man
