Misfire on cylinder 1 and 5

[Gobowiec]

Everything concerning sparks, MAF, TPS, EGR and injectors was checked. Cylinder pressure is 9.5 – excellent. My Wini is a “poor” European version, doesn’t have misfire checking, only two O2 sensors before catalytic. Even the engine is weaker – 150HP, same they put in Ford Scorpio (don’t even know if sold in USA, cant find forum for it). I don’t get codes using laptop and ELM adapter. So with Snap-On – no codes. They even ran self-diagnosis using Snap-On and this also didn’t show any codes. I’ll try to check timing with the lamp. Can someone pass manual how to check/set timing, CMP and CKP to [email protected] ? I’ve been told that Windstar’s often have problems with camshaft. Also that timing I get from OBD2 is the timing from PCM. That’s why I get through OBD2 reading of 15-16 degrees (should within15-20 ). Now I have to check if the sensor is set 10+-2 degrees. When I read O2 sensor I get 0,2 – 0,7V and can’t find any vacum leaks, so I think this is not the problem.
Is this a new problem? For me not. I have it since I bought the car. First engine start is normal. Every next is more or less problematic. Sometimes I have to press gas pedal. The engine got new valves and gasket shortly before I bought it, but the previous owner says that it was like this before the repair. Maybe its because of LiquiMoly that was added to the oil – I wrote about it here http://www.automotiveforums.com/vbul...d.php?t=906420

Ok, to check the timing with the timing light, you clamp the inductive pickup wire around the #1 plug wire (top front left of you). Don't connect it, just clamp it.

Connect the supply lamp to your battery (+12V and ground).

Start your engine. Reach operating temperature (90°C) and turn it off.

Disconnect the SPOUT connector.

Turn engine on again, turn off ventillation. Put it on drive with handbrake.

Point the timing lignt at the pulley and see if the timing mark (on the pulley) is aligned with the timing pointer.

If it's not aligned, you have a misconfigurate PCM.

To set the PCM, you need to install a good OBD2 program on your laptop and try to do some tuning.

You don't need to check your CKP and CMP, but if you want to do it, connect an AC voltmeter between pin 5 and pin 6 of your SPOUT connector. Start your engine. If you have a voltage greater that 15mV, your CKP work.

For the CMP sensor, connect the positive of the DC voltmeter on the center pin of the CMP, and the negative on the ground. Let someone crank your engine and read voltage at same time. If the voltage is greater than 5V, it works.

So what would be a good OBD2 program for the ELM327 on a laptop?

Here is the best program for setting up the time ignition advance: AutoEnginuity PC Scan Tool: http://www.autoenginuity.com/downloads.shtml

For GM, JET Dynamic Spectrum Tuning is also a good program to tune your car: http://www.jetchip.com/JET_Chips_Modules.asp You can download a demo. It cover some cars: camaro, firebird, corvette, impala, cadillac, GM truck. JET Performance Programmers can also tune some Ford cars.

For just read car information, such fuel consumption, RPM, speed, engine load, fuel pressure, mass air flow, water temperature, timing advance, intake air temperature, intake manifold pressure, gas pedal position... use ScanTool.net:

if you already replace the plugs,wires,injectors..... well try to change ur PCM or reprogram it....
