4afe ignition timing

[goldrat]

im trying to check the ignition timing on a Bigbody GLI with a 4afe. however, the degree indicator is a metal tab that covers the width of the crankshaft pulley which prevents you from matching marks with a timing light. its unlike other engines wherein the degree indicator is on the engine block and there is a timing notch on the pulley. can i set timing with just the diagnosis port, put a clip in E1 and TE1, turn the distributor until the check engine indicates a no code signal?

to request diagnostic trouble code you jumper terminals E1 to TE1, same thing when you adjust the ignition timing. the malfunction indicator light normally does not extinguish until the jumper is disconnected. for a 4A series engine (4AGE, 4AFE, 4AGTE.4AF), the stationary timing mark is on the plastic timing belt cover and the crankshaft pulley/harmonic balancer mark is on the inboard lip of the pulley. in time, the mark revolves around the crank pulley hub which makes the timing mark unreliable and inaccurate. if there is something other than the timing mark on the timing belt cover, it must be an aftermarket add on
