Section: 6E (VIt)

Date: May, 1984
Subject: LOW SPEED DRIVEABILITY
ON 2.8L CODE 1 AND 5.0L CODE 7 ENGINE

Model and Year: 1982 CAMARO
TO: ALL CHEVROLET DEALERS


On some 1982 Camaros with 2.8L V6 or 5.0L V8 CFI engines, a low speed driveability condition may develop. This condition may be a tip in stumble, low speed surge and roughness, or both. The condition may be a result of rich mixture due to malfunction of the canister purge solenoid.

On vehicles which exhibit the above driveability condition, check the canister purge solenoid as shown on the following diagnostic charts.

When the diagnostic check indicates replacement of the canister purge solenoid is necessary, use kit, P/N 14066587 to replace canister purge solenoid, P/N 1997553 (last three digits are stamped on the metal solenoid bracket). This kit contains canister purge solenoid, P/N 1997642 (varnished coil) and protective cover, P/N 14066503. The cover is installed by sliding over the solenoid before mounting.

When it is necessary to replace canister purge solenoid, P/N 1997642 (late production), replace with P/N 1997642, but be sure to reuse the protective cover from the original installation.

Use applicable labor operation.
