my car idles, but now my rpm gauge just sits at zero, it doesnt twitch or move at all. when i gas it, it dies. what can be the problem? i plugged up the two hoses that were suppose to go to the tmic, the bac is getting vacuum from teh IC piping on my fmic, its getting less vacuum than before cuz smaller hole. y wont my rpm tach work? and y does it die when i give a little gas, havent driven it yet.

eric.

 

i also took out my ac at the same time when i put on my fmic.

 

Check your trailing coil if somehow they got disconnected during the install.
The tach gets it's signal from the coil.

 

how come it dies after i give it gas?

 

how do i look for the rpm signal from teh trailing coil? why doe sthe car die when i give it gas then it as teh engine slows down it dies.?

eric.

 

check for vacum leaks. check all couplers from turbo to tb adn then TB to engine. it sounds like a vac leak. adn for tach. unplug trailing coil then replug it back in.

 

Wait... Post a pic of your hose routing.... I think you have something fubbed up...

You pluged the MAF back in right???

Do you have your BOV vented to atmopshere now???... if so.. thats why the car is dying after you rev it and let off the gas.

The trailing coils have the RPm signal built into the wiring harness, as long as everything is plugged in, it should work. If I remember, there are two plugs for the trailing coil right???

 

i have my bov welded on my piping along with a nipple/bung for my bac. bov vented into the atmosphere????? i dont follow.


eric

 

when I bov is vented to the atmosphere you will hear a sound look woooosh or psssssssst because it is venting the air to atmosphere instead of routing it back into your intake. Most people have them going to the atmosphere so I'm not fallowing on why it would make your car die??? YOD knows alot more than me so hopefully he will chime in in a second.

 

Yea I dont follow the bov part either. Most people with aftermarket bovs vent them to the atmosphere and they only when to the atmosphere when you let off throttle after boost. He obviously isnt building boost if he just touches the throttle and it stalls. Is the idle solid if you dont touch the throttle?

 

i see. yea my bov is vented into the air like its always been even with the tmic, it only has one vac line going to the bov, which is T'd off with all the other stuff like the boost gauge and pressure sensor. there's also a nipple/bung near where i welded on my bov for the bac, do i have to reroute it for the fmic? there is an extra nipple on the greddy type s bov, that was never used, i havent seen it used by anyone. wat does that do?

eric.

 

idle is a little jumpy, car shakes, but i cant tell by the rpm cuz it doenst work

 

the smaller nipple on the greddy type s is supposed to be left alone but the larger one of course is to be hooked up to a vac source.

 

Maybe the bov is leaking at idle. Try doing this Eric: loosen the screw until you can hear/feel it leaking and then tighten it 1/3 turn. That's how I adjusted mine. Did you try the carb cleaner/starter fluid to see if you have a leak.

 

ok cool. imma going to unbolt the trailing coil to see if theres anything under it that i probably accidently unhooked. could it be that it dies cuz i plugged up the two vac lines that used to go to the tmic? the only other things i did with the car was clean the engine bay and remove my ac components, everything but the thing at the dash.

eric.

 

k thanks stan, ill try setting it, might need to be set different since longer piping on fmic. or something.

eric.

 

my car doesnt even stay idle now so i cant adjust the bov. is it becuase i broke my relief s.v. on teh vac nest?

eric.

 

its the one nearest to the firewall, one of the four box things on the vac nest.

eric.

 

Solenoid? The little circle part that sticks out? I think that's only a small filter, I broke one off before and drove it like that until I removed the whole vac rack.

 

i took off the trailing coil and didnt find anything that was loose, except for one white plug all the way at the bottom but then theres nothing that connects to that. and my car still wont idle nor the rpm works.

eric.

 

y?

 

Did you check to see if all the spark plug wires are firing yet? That would be my guess. Test the resistance on the coils per the FSM. Even though you might be getting spark from the coils they might not be travelling to the other end at the spark plug.

 

Check the MAF again! You still have it right? It's still turned in right!

 

Doesnt sound like the afm is plugged in, or there is a big leak between. Perhaps he didnt plug the hole left over in the TID, where the old BOV went.

 

the afm is plugged in, if it wasnt the car wouldnt turn over. i even unplugged it and plugged it back to in to make sure. there is no hole on my tid becuase its just a 3"pipe.
