84 Celebrity 2.5 Timing

Thanks for the responses on #1 cylinder, forgot to ask when timing this engine - does it have anything that needs to be unplugged, or just plug the vacuum line on the tbi that was hooked to the air
cleaner cover and proceed? Thanks

The only thing to plug, when timing an engine that has a distributor, hence the ability to set timing, is the vacuum advance line, if it has one. Some distributors back then were already computer controlled in which case there is nothing to plug. GW

The timing set procedure should be spelled out on the underhood emissions label, IIRC it will tell you to jumper the ALDL.

It should tell you on the underhood label thats usually on the radiator support or sometimes on the air cleaner housing. On all the computer controlled GM cars that I've had to time there is a brown/white stripe wire that needs to be unplugged. The label will tell you where it is under the hood.
