My Aurora had a slight hesitation or rpm surge at about 1500 rpm. disconnecting the electrical connector from the EGR valve and the problem went away.
ck for vac.leak or bad iac valve
on a 98 ford taurus what are the symptoms of a bad hydralic valve lifter
A bad EGR valve in a 2000 Saturn can have several symptoms. The EGR valve can cause misfires, the valve can cause vacuum leak style problems. There could also be an engine knock.
it bangs when you put it in gear
Check engine lit goes on.
Yes.
valve should rattle when shook, and when engine is started it should have a good suction.
No.
An engine with a bad intake valve is likely to backfire frequently. This can easily destroy a carbuerator or throttle body. The same symptoms can be caused by a poorly adjusted rocker arm or poorly timed cam and distributor.
engine cranks over but will not start.
Bad spark plug or wire? Bad Valve or piston? (do a compression test)
No. In fact the aurora borealis and the aurora australis are very beautiful sights.
