To get a zero result your hex data would be 00 00. And yes I remember that 200 straight 6, and the vac advance screw, had one in my Maverick. Every car I ever was called over to sort this question out on it was obvious. Chapper7718 answered 3 years ago Thanks for all of the great info. Monitor the Cam Retard Offset. To compensate for a negative reading, rotate the distributor in the counterclockwise direction.
With all the new parts it runs great. On my 96 the distributor is adjustable because it has an elongated slot cut in the holder. Never assume that you are anonymous and cannot be identified by your posts. This will give me a noticeable change in data and I know exactly where the problem happened and I can start examining the data frame by frame. I put in a new fuel pump relay because it was a cheap and easy thing to do-- no change. Start the engine and bring to normal operating temperature. Drove the truck and no change.
If the Cam Retard indicates a value of 0° ± 2°, the distributor is properly adjusted. I drove it around the parking lot and it seemed fine so I headed home in the truck. Just always wondered why Torque did not include it in an otherwise very nice app. You can see that studying the drawing before disassembly in the websites that depict it, is all your technician needs to set you straight if you have trouble. I can easily confirm this part, and will when I get a chance later this week. Wow, there is alot of information going on in this thread that has me believing the answer to my neighbors motor we have recently installed.
Record the data before the problem happens and, for a bit, after it happens. Some will say you have to have it but they apparently never tried it without it like I've done on millions of cars. Start the engine and bring to normal operating temperature. She called me and said the truck started running rough, had no power and the it shut down. This I was told has to be 0 the give the computer its base to be able to control timing. Turn dist a hair, clear the code, start the truck.
Still curious where the hex data is coming from if you are not getting 62… back. If the response matches the example given then Torque variables A and B are correct. To be continued at some point…. My understanding is that the results are not accurate unless the rpm is greater than 1000, which might explain behavior of the 7F22… message. The specific rpm mentioned is just 1000 rpm and that is all. Rev motor up past 1500 and let off.
So I got a new distributor. If you do there is nothing to setting the timing on these trucks. What I remember though was after I had the intake coolant leak fixed and they also replaced the timing chain that the camshaft reading was -3 and I thought that they might have been off a tooth when reinstalling the cam gear on the cam. Not sure how well engine will run at those thresholds though. I can't go + any since the cap hits the plenum.
No signed vs unsigned decimal, strictly raw data. If the Cam Retard does not indicate 0° ± 2°, the distributor must be adjusted. If you've to reset a code. I just checked a v-6 with 200,000 on it and the cam retard was off -16 degrees. Do you think they create these terminology deboccles and then hand out technical manuals to everyone? Again not sure if this means anything.
Oh and by the way. If we had the service tool, great. The problem has started a few to a few hundred frames before the light comes on so you can not see a drastic change from one frame to the next. However I would double check your tests. It could be a possibility on a 4. Yes you can get it close but you can not be sure it is correct without equipment. Because there is a mistake.
Rotate the distributor as follows: 4. Tighten the distributor hold-down bolt to 3N·m 25 lb. Repeat step 4 until 0° ±2° is obtained. Dannyl answered 3 years ago Out of phase is also like a ranger driveshaft, you can almost get it 180 out, but not quite, if you tighten the yoke onto this two stage shaft out of phase and assemble? Not sure how to interpret these readings. Cal engines use a distibutor hold down that allows only one position, no matter what the offset is, it's not adjustable. If not, the infamous P1345 code.
