Fuel Injection Kit for Intake Valve Decarbonizing Information
1Fault
- Hard start or long crank
- Misfire or rough idle
- Does not start
- Warning light
- Check engine / Service Engine Soon
- P0300
- P0301
- P0302
- P0303
- P0304
- P0305
- Rough idle, crank no start, extended crank or misfire, with the engine warning lamp on and DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 or P0308 set.
- When the engine is cold, compression on multiple cylinders may be zero.
- The engine may pop through the intake or exhaust while cranking, and the spark plugs may be fuel fouled.
2Finding the cause
Possible causes
- Major carbon build-up on the intake and/or exhaust valves from fuel contamination or incomplete burning of the fuel; misfires should not appear before at least 8,000 km (5,000 mi).
3Correction
Repair
- If there is no valve damage and no cam follower out of place, perform the cleaning procedure to free sticking valves and remove carbon from the valves and pistons.
- If valves are damaged or cam followers are out of place, make the engine mechanical repairs first and then perform the cleaning procedure to prevent a return.
- Fill Cleaner Kit J-35800-A with about 473 ml (16 oz) of Top Engine Cleaner and set the air pressure at the tool to 260 kPa (40 psi).
- With GDS 2 or a scan tool, command engine idle to 2000 rpm so the engine does not stall.
- With the engine at operating temperature in a well-ventilated area, slowly and carefully induce the cleaner into the engine, taking about 3 minutes.
Parts
- ACDelco Top Engine Cleaner is 19355198 (in Canada, P/N 19355199).

Caution
- Inducing too much cleaner at too low an RPM, or stalling the engine with too much cleaner at once, may hydro-lock the engine and bend a connecting rod.
