i was just thinking about it yesterday and today, since i fixed a toyota echo that was smashed in the front and hit a tree, so it destroyed pretty much everything in the front and touched the intake mani, now when i started it up after i was done putting everything in it also had a jumpy idle and shut off, and my car once in a while jumps the idle and turns off, on the echo i took the intake mani off noticed it was cracked, sealed the cracks and made sure the vaccuum lines were all in the right spots and werent damaged next thing i knew the car was running like a champ, well i was thinking, my car maybe a gasket on the intake mani or s/c might be busted or the intake mani isnt on good enough or a vaccuum hose is not on right, let me know guys
