CobraKevin Posted December 22, 2003 Report Share Posted December 22, 2003 From the beginning... Went to see LOTR again with some buddies tonight at Easton. On my way home, I turned left at the light heading toward 270 S when a Civic comes flyin around the corner. I give it a little bit of gas in 2nd gear, but let him in front of me onto the onramp. He guns in on the onramp, I follow suit (though in 6th gear now). Probably doing about 80-90mph in 6th at the bottom of the ramp, I downshifted to 4th quickly in order to accelerate fast enough to blow right by him instead of the gradual pull in 6th. Well, when I downshifted to 4th, the engine made a strange noise as well as the transmission. Service engine soon and battery lights came on, car would go into every gear but wouldn't accelerate (similar to breaking a driveline part). I pulled off to the left side of the median by the wall and came to a stop. I turned off the car, called my parents (who were asleep) and got the answering machine. I started the car and it did infact start, and amazing accelerated in first gear. I went through all gears up to 6 fine with the exception of a faint, but quite noticable hissing noise coming from the engine. The fact that it went through and accelerated through all gears tells me it's not a transmission, rear-end, or any other driveline problem. When I got home, I got out the Digital Camcorder and recorded a short video of my car at idle in the garage, hood up. The hissing noise is QUITE loud and obviously should not be there. I'll try to upload the video sometime tomorrow, but I'll take any ideas ASAP. The belt on the supercharger seems to be intact and still connected, but there was some air pressure pushing out of the engine compartment. I'm trying to be as specific as possible to narrow down the possibilities, so thanks for any help. [ 22.

Hwilli1647545487 Posted December 22, 2003 Report Share Posted December 22, 2003 Sounds somewhat similiar to when a turbo car pops and IC hose. Check all your hoses? Do you have an OBDII Code puller? Quote Link to comment Share on other sites More sharing options...

CobraKevin Posted December 22, 2003 Author Report Share Posted December 22, 2003 I went out in the garage to do a little more research. I found that when I turned on the car, then turned it off, when the car goes off a noticable suction noise occurs. Then, after the car had shut off, with the hood open, a quieter hissing noise can be heard best from under the hood (if looking at the engine from the front of the car, the hissing (as if air is leaking) is loudest in the front left of the engine compartment, like between the intake and engine block). A hose leak of some sort definitely sounds to be a possibility, but I couldn't really see anything suspicious. But then again like I said, I'm not very mechanically inclined.

SupraGlue Posted December 22, 2003 Report Share Posted December 22, 2003 Watched the video and it sounds like it could be a blown intake manifold gasket. Quote Link to comment Share on other sites More sharing options...
CobraKevin Posted December 22, 2003 Author Report Share Posted December 22, 2003 Welp, problem is fixed. Hensler to the rescue. VERY minor problem, just the vacuum hose on the back of the blower (or engine, behind the block) popped out. James popped it back in and idle returned to normal. Fowler, since James hardly if ever reads the board, make sure you tell him thanks from me again. I really appreciate it. Quote Link to comment Share on other sites More sharing options...

Hwilli1647545487 Posted December 23, 2003 Report Share Posted December 23, 2003 Told you it was a hose I'd put a ZIP tie or clamp on it to prevent it from happening in the future. Quote Link to comment Share on other sites More sharing options...
CobraKevin Posted December 23, 2003 Author Report Share Posted December 23, 2003 Well, now there's another small problem. I went to work today and stalled twice on the way there (unexpected stalls), then on the way home just about every damn time I pushed in the clutch and came to a stop, it wanted to stall. I'd fight it by tapping the gas to keep the rpms up. Also, I noticed that I was not making peak boost throughout the rpm range. In 3rd gear when floored, my car made peak boost until about 4500 rpms, then slowly dropped to roughly 7 by the time I hit 5500. When I got home, I unhooked the negative battery cable for about 15 minutes, hooked it back up and drove the car around. The good news is the stalling problem seems to be worked out. The bad news is the boost leak is still there. Could that be just another hose, or possibly something more major? Quote Link to comment Share on other sites More sharing options...
