I swapped my gsr cams out with some b16a2 cams suddenly it's idle surging. I made sure the coolant was topped off, checked for vacuum leaks even cleaned the iacv. Still does it. It doesn't always do it. But sometimes it'll surge so low my car will die. How do I tell if it's the tips or iacv. Someone told me if you in plug it your motor should rev up an idle high. Is this true. When I do that my car just dies. I don't have access to a volt meter to check voltage at the tips.

 

why switch out your cams? GSR and B16 cams switched gives you absolutely no gains. in either head.

 

They do in a turbo application but I decided not to boost it and sold my kit with the cams

 

So lemme see. You swapped in the stock cams for the engine now it runs like crap? Are you still running the ECU that was chipped for the old setup?

I suggest you list all mods still on the car, or if it's back to stock and what car this is in cause it could be in a Jeep Renegade for all we know.

 

What car?

Did you bleed the cooling system?

CEL codes?

Does engine have an FITV?

 

They car should be irrelevant. But for ***** and giggs it's in a 99 ek 4 door. The ecu is chipped with a b16 basemap. The Motor is basically stock besides flat valves and BC valve train. The tune isn't the problem. I had stage 2 cams in it and it ran better than this on the same tune. All I'm asking is how to determine if my iacv is going out.

 

Jdm b16a in a 99 ek. Yes the cooling system is bled. No it's not throwing any codes. And I'm not sure if that motor uses a fitv. I'll have to look at I tomorrow. But it does it cold and hot. So I don't think that's the cause either.

 

Why should it be?

...and car information is required for ALL tech threads, so follow the rules.

Why are you so prone to draw potentially false conclusions? If you know so much, why did you need to create a thread?

 

Jesus. I created a thread asking about the iacv. Not my tune. I've swapped multiple parts out on it with the same tune. And never had any problems.

 

Good luck to you.
