Hi folks-
'93 LX auto ...I recently replaced my head with an ebay special...got everything reassembled, at this point I have most of the kinks worked out. It starts up, idles fine, drives reasonably well, no codes...but it seems a bit down on power, and I get some knocking/pinging when the engine is under a heavy load. So I decided to double-check the ignition timing.
I attached my light to plug wire #1, jumped the ECU jumper, ran the motor until the fans came on - it's idling at right about 700/800 rpm...but when I look in the hole with the timing light...I can't see the timing marks at all. I'm looking down into a vacant hole, at the head of a bolt on the flyweel, not at timing marks.
If I get really low to the ground, and look through the hole at a crazy angle...I can just barely see the bottom of that metal tab that the marks are stamped onto. It appears based on that, that my timing is waaaaay off.
I've rotated the dist. to it's fullest extent both forward and back, and the best I can do is when I rotate the dist. fully clockwise, the metal tab slowly comes down to where I can barely see the bottom edge (but can't see the timing marks). I don't even know for sure if it's the tab with the marks on it...hell it may be something else.
My first question is that I can't figure how my timing could be so far off and yet the car runs so well - second is that I have no idea how to get it any better. Could it be the timing light? I don't think it's possible to install the distributor wrong (keyed connector)...any ideas?
