Hello I am new to this. I have never posted a question before. Please I need help!
I did not know how to start a new post so I looked for similar problem. 1995 Sidekick 4x4 Man Trans, MFI 1.6 16v Calif. Emissions,
Problem Injector Pulse width 4.8ms at idle.
Black smoke and strong fuel smell from exhaust pipe. Runs great, idles great has power, no hesitations but runs very rich.
No DTCs
Blinks 12
Tech 1a : No DTCs
Basics have been done, Good compression 180s min difference 5psi, Ignition and spark plugs and timing at 5 BTC. Fuel pressure Koeo 36 then 31 and and hold above 26 psi for more than 1 min. Although the following data stream from Tech 1a shows:
Engine speed 788 rpm
14.8 Volts, 16 % charging.
Rich status
AC and Power Steering off
EGR Temp 142F
EGR off
Idel switch on, Fuel Pump On
IAC 28 L/min
Idel Adj Mont 0%
5 to 17 degrees spark advance
Injector Pulse Width 4.8 ms
St Fuel Trim 128
Lt Fuel Trim 117
HOS .894 mv Activated but not sure if its switching 1200rpm 1500rmp or 2500rpm?
Close Loop I am determining by causing a vacuum leak pulse width goes down and and spark advance too.
TPS .86 Vlt 0 degree angle
ECT 147F ( This is error of Tech1a) Tested at Pin 9 ECM/ECU .66vlts 320omhs at ECT disconnected ECT connector pin 9 back probe Idle goes to Ref. Voltage 4.7 182 degrees infared.
MASS 2.4 g/s
IAT tests 75 degrees 1900 ohms
Parts new Fuel press regulator leaked pulled hose, O2 sensor resistance out of spec., CAT damaged,
EGR and Sensor, CEL on DTC 51
Spark plugs wires and CAP rotor and oil change fuel saturation
Timing Set to 5 BTC Ground Duty Cycle Connector
