I got off the freeway after a hard pull through 3rd to 4th and my car was Idleing terrible. The Rpms stay around 800 so its not surgeing but it sounds like a damn v8 with a wicked cam. It is also pulling only 10-12 vac on the boost guage. Any help would be appreciated.

sorry forgot to mention that she normally pulls 20 or so vacum.

check your boost sesor aka map sensor on the driver side firewall. Has happened to plenty of us before. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Checked the sensor everything is connected. This is so weird. I have checked everything I can see and I don't see anything disconnected. Also I've noticed that I now run 5-10 degrees(Celsius) hotter than normal and the weather hasn't changed. I'm going to take it in on tues unless you guys can think of anything else. https://www.nopistons.com/forums/pub...1047683561.gif https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Just be safe and do a compression check: You could of blown off a line/lines somewhere. You still have twins?

Yeah, I have still have the stock twins(saving for GT35/40). If the compression check comes out positive and it is just a hose somewhere I'm going full-Non Seq. I just bought a turbo manifold and Y pipe already modded to do it.

check your belts. I know it sounds dumb.



That sounds like what happens whenever you pop your alt,water pump, main drive, etc. belt off.



You also might want to check your spark plugs.



Does it feel like you still have full power???

LannyRX7 07-14-2003 05:10 AM
oh yea...also check your power fc to make sure you didn't put it in that umm..



that mode, damn I don't feel like moving (long work day).



the screen that says:



Normal

Option 1

Option 2

Option 3

Option 4



that one. make sure it's on normal cause all of the other options make it sound like it's caming.

Possibly a burnt tip of an apex seal. Pull the intake elbow attached to the throttle body. Pull the EGI Main relay(no spark, no fuel). Have someone crank the car over and hold the throttle open. If you hear six good pops and no swooshes your motor is probably good. If you hear a swoosh you have a blown motor. This is alot cheaper than a compression check. Just remember to leave the spark plugs in and remove the EGI Main relay.
