Alright, here's my situation. I've got a b16a1 swapped into a 90 civic h/b. I've been troubleshooting the bugs out of it since I got it installed, and suddenly I have yet another one.

When I have the car in gear, and give it more than just a little gas, I get a fairly strong vibration. Nothing that worries me a lot, just enough that I don't like to gas it too hard at all. Now, if I take it out of gear and give it gas, it revs fine. Also, if I get up to a certain speed and drop it into a lower gear, revved fairly high, I get no vibration.

Does this have something to do with my throttle cable, body, etc. ? If so, what can I do, and does anyone have any pics that might be helpful?

 

Also, when I start up the car in the morning, the gas pedal often sticks to the point where I have to push it kinda hard to rev the engine, just for that first time. Is this related?

 

I had a vibration when I did mine. My rear mount would vibrate on the rear cross member. The throttle cable sounds like it needs to be replaced.

 

sorry. I had to bend the lip of my rear crossmember down some to get rid of it

See, I don't know where that is... Can someone post a pic?

 

Take off the rubber hose to the air cleaner...this is the ends of the shaft where the butterfly valve is on the end of the intake manifold..a few squirts on either end....flap it open and closed a few times squirt again...4 of 5 cycles adn its clean for 30-40K miles.

 

I need pics. I could stare at that sentence all day long and not understand what that means.

 

take off the intake pipe. Look into the intake manny. do you see that flap that covers that hole? That called the butterfly. You can stick your finger inside the manny and push it open. Do this while the car is off.

 

I just installed a short ram air intake, could I have done something when I did that?

 

Alright, I just took off my intake pipe and looked inside the manifold.. All I see is a gold thing covering the inside with a black strip across the middle and a couple of screws in it. Can anyone direct me to a website that'll show me diagrams or pictures of this whole apparatus?

Really want to get this thing running smoothly, nobody has advice?

 

WRONG AXLES/ OR MID SHAFT WRONG!!!

These are the axles that shipped with my Hmotors swap.. I don't think they get them wrong all that often.

 

If this helps, it also vibrates a lot when it idles too. In addition, sometimes it vibrates when I throttle and sometimes it doesn't. It comes and goes.

 

poly hasport mounts being used?

 

Yeah, hasport mounts.

 

Bump, still happening. I took it to the local Tires Plus type place and they charged me $20 just to tell me that it was my motor mounts. I don't think they even felt what I was talking about. What a waste of time.
