problem with ported upper installation. HELP!!! **FIXED!!!**

Ok yesterday me and jeremy (Horse) put my ported upper on my car. We got everything back together and started the car up... started fine then went down to where it idles and started sputtering and dropping to like 200 rpms and eventually died. Well we looked under the hood and realized we forgot to reconnect the egr pipe to the egr valve... so after an annoying fix with that we finally got it put into place and started it again. It did the same thing. This time though there's a high pitch whistling sound and itll sit there and idle rough for a while, but takes longer to actually stall the car. So yesterday i was driving it cause i thought id just need to keep the idle RPMs up so the car wouldnt die, but as im driving it i would be driving and then lose all repsonse from the throttle... it even stalled out on me once so i just took the car home to let it sit and drove my dads the rest of the night. IM not really sure whats wrong here... the only thing that me and jeremy could come up with is that maybe the metal gakset that goes between the EGR valve and the upper intake is shot and is creating a bad exhaust leak so im going to try replacing that today. Does anyone else have any suggestions on what might be wrong? Im pretty sure ive connected all the vacuum lines but Ill be double checking that today as well. Any ideas?

I'd double check all the vacuum lines and sensor connections. Is the gasket between the upper and lower good? It sounds like a bad vacuum leak, to me.

 

[Zim]

yeah i replaced both the gasket between the upper and lower, and the throttle body gasket

 

[Zim]

Corey Any Ideas???!!!

They is a gasket that goes between the EGR and the upper intake. you might have a EGR problem. You could have the vacume tubes hooked up wrong. Tke the vacume tube off the saucer shaped vacuum cannister and hold your finger over the vacuum line and see if it changes anything. Next chech the cannister by when it is cold see if it is holding a vacuum take a hose on it and use your mouth to create a vacuum ( if you dont have a Vaccume tool) and see it it holds.

Did you use your EGR from your car???

 

[Zim]

yeah i used the EGR from my car, just swapped the intake over. Im gonna go try those two things right now... but before i did this i wasnt having any problems with my egr, why would it act up now?

 

[Danger Dude]

You just never know

 

[Zim]

ok i think i found the problem. That line that connect to the underside of the intake was loose, i pushed it in as much as i could wihtout compeltely taking of the intake again and it does run better.. it doesnt stutter out and die anymore. Now i just gotta make sure that thing is nice and tight on there. I dont know how that cme off, i specifically remember putting it on there nice and tight. Basically i just listened where the noise was coming from and stuck my fingers under there to see if i could feel anything. Sure enough it felt loose and i could feel a vaccuum suck my finger against that area so now i just have to get it snug on there. Thank god...

 

[Zim]

im gonna run down to the gas station and see how it does on a short drive. ILl be back and ill update you on how it is

 

[Zim]

alright.. well it doesnt stutter out and die anymore but it still isnt driving right. If im goin faster than like 35mph its like the transmission puts itself into neutral and just wont give any reponse to the engine. Alsmost like my car turns off, then itll start responding to the throttle again out of nowhere. This frickin blows... god dammit

 

[Danger Dude]

That almost sounds like a Throttle Position Sensor. Did you use a different T/B

 

[Zim]

not a different one no... we half shafted the TB when we took it off though

 

[Zim]

the thing is its still whistling under the hood when the throttle is just hardly engaged... its a pretty loud whistling noise and i just cant seem to tell where its coming from. This is really gettin me discouraged, now i have to wait longer to head back to school cause im gonna have to take my damn car into a shop.. god dammit this blows

 

[thirstymate]

have someone run your engine up while you spot the leak .. it sounds like a throttle sensor to me, electrical parts are real sensitive sometimes and simply moving them around can screw them up. could have loosened the connection while you had the tb off

 

[thirstymate]

that would be why it only happens sometimes

 

[thirstymate]

also is it a cut and weld intake.. if so they could have missed a weld
dont know if you have the time but if it is a cut and weld intake id take it back off and pressure test it. if it leaks, then thad be your whistle

 

[Zim]

no its not cut and weld...

 

[Zim]

i think im just gonna bite the bullet and take it to a stupid shop.

 

[97Stallion]

Mike, well I would try first, you might have gotten the idle air control and the EGR connectors mixed up, so that could be a problem. So it's not relaying any info to your DFPE? or your IAC. You could try that cause they look the same, and finally I don't think anything is really wrong with the intake or your vaccum, maybe you half shaft and polished something too much? But I'd be willing to bet you got those connectors mixed up.

 

[Zim]

can you tell me what those two look like? are you talkin about the things that plug onto the sensors?
