help quick! was doing vacuum job
ok, so I FINALLY finished my vacuum line job, and after getting it done, I get in to start her, she has some trouble starting, and once she starts, its backfiring alot and feels like its misfiring, so I let it warm up, it gets to operating temp, idle is steady and shes running ok, but I still got my check engine light on, I take her out and it was ok for a few min, then it just starts to bog alot and stutter when accelerating and goes like bup bup bup bup bup bup and its really weak, then when I come back, it wants to die when Its idleing, and then when I let the clutch out, it would bump up and down from about 100-200 rpms and almost die but not quite.... what should I do? how do I check the engine light?

ok so I got, air intake thermorsensor (Engine) and throttle sensor full and short range, codes 11 12 and 18
WTF are those lol |
http://www.scuderiaciriani.com/rx7/engine_codes.html That's for the ecu codes. Sounds like limp home mode to me. Check the codes, and get back to me.
|
You plugged your tps back in, right? Did you mess with the tps at all besides unplugging it? Also, I know everyone always says this, but check to make sure your MAP sensor hose is connected.
|
check to see that they are plugged in.
|
Ha! He didn't plug in his TPS.
|
Ha! He didn't plug in his TPS. Just wait till he finds out thats his problem ;) :doh: |
ok well, I plugged my TPs sensor in, and all codes are off now, I reset the ECU, but my car still bogs and wont accelerate worth crap, I still have perfect idle
|
Did you check you MAP sensor? Vac hose that goes to a little black box on the firewall near the brake master cylinder. Make sure you have it plugged in to the correct nipple on the throttle body too. There was a guy on here a while ago that had it ont he wrong tb nipple.
|
Can you describe what you mean by 'bog'? Are you just not getting boost, or is it backfiring? And you are not getting a check engine light, right?
|
yeah I checked that, made sure the filter was pointing towards the LIM too
|
no check engine lights, my car idles fine, when I start to give it light throttle, I hear like a rattaling noise when I Start to give it any boost, and it just accelerates like crap

I get perfect boost though, my engine will go all the way to redline with light boost, and the noise I was hearing was my boost hesitating like mad because of my engine hesitating, my boost needle would bounce all over the place.
|
I guarantee you you probably left a hose off somewhere. Just retrace your steps and you'll find it
|
anyone know??
|
Keep looking man. The car ran fine before you started right? So then you forgot something somewhere. Go over everything one at a time. I would pull the UIM back off and check the lines too.
|
I took mine to this place out in Skokie to have th engine smoked. I would suggest you find a way to get the intake sealed while doing this test.
|
?? WTF are you talking about?
Engine smoked??anyone here have a clue what this guysis talking about? |

Originally posted by Fd3BOOST ?? WTF are you talking about? Engine smoked??anyone here have a clue what this guysis talking about? What they do is hook up a machine to the vacum hose on the master cylinder and create pressure thru the system while sending a "smoke" thru the system. With the pressure the smoke will find the path with the least resistance... the leak. It creats up to about 7psi. |
I had an idea like that a while back, but I didn't have the proper tools. Now I just use compressed air, and listen/feel for leaks.
|
Ok never heard of that.
|
ok well it turns out my wiring harness on the ignition coil rack was reversed!!! its all fixed now WELCOME TO FULL BOOST LAND!! WOOOOOOOOOT!!!!
|
good to hear.. happy boosting
