car idling high, after installing distributor Options

[JPATTT]

Have a 1998 Toyota Celica 2.2 5sfe. After installation of distributor car idles at 2000 rpms. I read that the ecu is suppose to adjust the timing is this not true and is this my problem?

Obdii does adjust its timing by itself. Maybe try resetting the ecu.

Like Silly said, try resetting the ECU first. Another possibility is maybe by chance you unplugged the IACV.

Just reset my ecu and no change still idles at 2000rpms. Checked all connections and all looks fine. I'm completely stumped

After warming up does the idle drop down?

Umm, I dont think the ecu will 'set' the timing. It just makes slight adjustments based on readings from the knock sensor. Realize that the ECU varies the time at which the ignition coil fires, it cannot change when the rotor physically passes the contacts within the distributor cap.

Base timing must be set with the E1 and TE1 contacts jumpered in the OBD1 diagnostic port that is near the brake/clutch mastercylinders under the hood. Use a timing light to set the base timing to 12 degrees BTDC.

At least this is how it is on my 94 GT, but it could be different on the 98 because I believe you have a crankshaft position sensor the older models dont have.


Is it possible to rotate the distributor once you loosen the two bolts attaching it to the head, or are the bolt-holes not slotted so that you cant rotate the distributor?

I was kind of wondering about that myself. Surely you have to get the distributor set remotely close, even if it does set it by itself.

Unfortunately no adjusting bolts. Just one bolt and no adjusting.

96 and up you cannot adjust the timing. 94-95 you can turn the dizzy. If he has a 94-95 dizzy he could in theory adjust the timing but over time the ECU will adjust it. Easiest thing to do would be to check the timing to verify it is where it should be.

Check for any cracked or broken or loose vacuum hoses or ports, you probably caused some collateral damage during your repair.
