Heza Posted October 23, 2004 Report Posted October 23, 2004 I think i may have been on this subject before, but what are the symptoms of improperly timed cams on a 3.4? shitty idle, shitty running, wont start. Quote
GrandPrix34 Posted October 23, 2004 Report Posted October 23, 2004 an invisible wall that wont alllow the motor to rev past a certain point... with the DOHC, a cammed idle soudns awesome! Happened to me when one spark plug wire was busted, i was running on 5 cylinders and the car sounded real badass....but it had the accelerationg of a honda though.... Quote
DaveFromColorado Posted October 23, 2004 Report Posted October 23, 2004 depending on which cams are off, and how far, it could range from anything to an awesome torque in the bottom end and nothin' over (example rpm) 4k - that RPM range could be just 'bout anywhere, it could die off at 2500 rpm's - or it could be the exact opposite - nothin' on the bottom end, and all of a suddon at a certian RPM everything comes to life - or if all the cams are way off, it could just feel like shit from idle to redline. there's SO many symptoms of timing problems, that it's really hard to pick one thing and say "that's it!" I'd suggest pullin' the front valve cover, and checking the two flats on the cam to make sure they're lined up with TDC on the crank. --Dave. Quote
Guest Anonymous Posted October 23, 2004 Report Posted October 23, 2004 shitty idle, shitty running, wont start. Thats me. The engine does sound kinda badass, if it wasn't for the little puffs of smoke chugging from the exhaust. Quote
DaveFromColorado Posted October 24, 2004 Report Posted October 24, 2004 my 91 Z-34 has those same symptoms with a bad fuel pressure regulator.. --Dave. Quote
loominaz34 Posted October 24, 2004 Report Posted October 24, 2004 Wont idle but between 1800 and 5000 it pulls like a mofo and won't go over 5500. (personal experience.) Quote
Guest Anonymous Posted October 25, 2004 Report Posted October 25, 2004 It never acts the same from day to day. I dont know what to expect when I take it in. Quote
