i P0304 | tne scan tool indicates Diagnostic Trouble code {DTC} PO3O4: Cylinder 4 misfire detected.
Doscription
Misfire detection is accomplished by monitoring the crsnkshaft speed with the crankshaft speed fluctuation sensor whichis attached to the crankshaft.
lf misfiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence, and DTCP0301, P0302, P0303 or P0304 will be stored. Then, after the m;sfire has ceased, the MIL witt come on.lf misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and DTCP0301, P0302, P0303 or P0304 will be stored.
NOTE: lf some of the DTCS listed below are stored at the same time as a misfire DTC, troubleshoot those DTCS first, thentroubleshoot the misfi.e DTC.

The scan tool indicates Diagnostic Trouble Code (DTC) P]382: No signal in the Cylinder Position (CYP) sensorcircuit.
D€scription
The CKP Sensor determines timing for fuel injection and ignition of each cylinder and also detects engine speed. The TDCSensor determines ignition timing at stan-up (cranking) and when crank angle is abnormal. The Cyp Sensor detects theposition of No. 1 cylinder for sequential fuel injection to each cylinder.
NOTE: ll DTC P1359 is stored at the same time as DTC P0335, P0336, Pl361, P1362, P1381 and/or P1382. troubleshoot DTCP1359 first, then troubleshoot those DTCS.

Throttle Body
$;
Description
The throttle body is of the single barrel side-draft type.
The lower portion of the throttle valve is heated by
engine coolant from the cylinder head. The idle adjusting
screw which increases/decreases bypass air is located on
the top ot the thronle body.

Inspection
1. Start the engine. Hold the engine at 3,000 rpm with
no load {in Park or neutral) until the radiator fan
comes on, then let it idle.
2. Stop the engine, and check that the throttle cable
operates smoothly without binding or sticking.
. lf the throttle body pon is clogged, clean it with
carburetor cleaner.
. lf there are any abnormalities in the above steps,
check for:
Excessive wear or play in the throttle valve shaft.- Sticky or binding throttle lever at full close posi-
tion.- Clearance between throttle stop screw and throt-
tle lever at fullclose position.
81881, Bl8Cl engines:
There should beno clearance.
818C5 engine:THROTTLE LINK
There should be
