You are in the Ford Ranger
What is this discussion about?

Well, since you haven't told what engine you have, here are two guess for two different engines.
3L - Most of them ping all the time, even when relatively new, for all their life. Ford doesn't seem to want to re-engineer them to stop this. Only thing that will help is to pull some 'plug' (SPURT ? plug), which basically will retard the timeing and reduce power, which a 3L doesn't have much to spare. Or, use higher octane gasoline. There are some TSB which say to replace the coil packs. Sometimes this helps, other people that have done it say it doesn't help.
4L - See my message about 10 or so messages back. If a 4L pings, tighten the lower intake manifold bolts.

Yep, there are two engine temp sensors. One drives the temp gauge.
The other gives info to the computer. The one that feeds the computer will have 2 wires, one of them will be yellow with a black strip and will be twisted together (I think).
If the 'computer info' one fails, the problem usually is that it is difficult to start (and if/when it starts, it will run rough) when COLD. Basically, the computer thinks it is trying to start a HOT engine, and it will not increase the fuel delivery time needed for a cold start. After the engine warms up, it runs and restarts ok.
Since you peoples problems were HOT start problems, I didn't want to throw this sensor problem into the discussion, since all the problems I've heard of have been cold start problem. But maybe the sensor will fail in the other direction, and this then causes HOT start problems...
Might be worth replacing this sensor. I'm assuming you aren't getting any 'check engine light' being set. If so, PULL THE CODES first before throwing parts at the problem.

And, burning tranny fluid in a motor might cause lots of things, including pings. The vacuum leak from a busted modulator valve might lean it out enough to ping. Throw in some Dexron, and who know what you get.

Well that's four starts in a row (knock on wood)!! I've been reving up the engine before I turn it off lately! Hoping that will keep the string going!! Superstitious I guess! Don't know how long it will last!! Just like a riverboat gambler!

Sorry - my mistake. I have the 3.0 6cy in my Ranger. I currently use the 89 octane gas which I have done since I bought the truck. Have heard ping before but not like this, Just started within the past 6 months. Can it be the tranny fluid being sucked in? Just for info - called the Ford dealer yesterday to see how much the valve part was ($40) and the parts guy stated he didn't think this would be the cause as he has never heard of one of those valves going bad. One other parts guy told me there was no vacuum assist on the tranny.

you said you found the problem???
what was it? you mentioned timing belt, but what specifically regarding the timing belt?
Jun 08, 2005 (8:36 am)
I have an 89 Ranger 2.3 distributor-less. No spark on either side, its driving me crazy...
Jun 08, 2005 (7:01 pm)
I have a 98 ranger with the 4.0. Lately it's been giving me a problem first thing in the morning, it acts as if it's either starving for gas or spark when i put it in drive or reverse. When in neutral it idles perfectly. Also, i can be driving down the road and when i press the gas just enough to pass a car or speed up it will jerk as if it is missing or not getting enough gas. I was wondering if anyone had any suggestion as to wear to start. I've changed the fuel filter recently. I've done a completely tuneup (plugs, wires, and coil pack). I've been told it can be numerous things like the 02 sensor, temp sensor, and a few other sensors but nothing seems to add up. If any one can give me a little direction, that would be greatful.
#1310 of 2986 92 ranger 3.0 ECM Testing issues
Jun 08, 2005 (10:02 pm)
I have a 92 ranger with a 3.0. Yesterday it wouldn't start at all. Today it finally started but seems to be running on open loop in the ECM. Idles fairly well but very little response and power. When I went to check the codes it will not do any thing. One other thing, the fuel pump runs continuously but the fuel pressure is correct. The fuel pressure regulator is working properly also. It is as if the ECM is running on the Prom Chip only and none of the other devices make any difference. While running I have disconnected the Mass Flow air valve, Throttle position sensor, and Idle air Control valve. None of them make any difference whether plugged up or not. Can you take the ECM somewhere and have it checked to see if it is operational, I hate to spend $150 to $200 on a replacement only to find out it was not the problem.
#1311 of 2986 Re: '98 Ranger high idle [pjama]
Jun 09, 2005 (9:34 pm)
I have the exact same problem as you with a little more drama. I had some friends help me change out the spark plugs/wires. In order to get to the plugs located on the right side of the engine we had to remove the manifold. We put everything back together and everything worked - for two days. Then the idling started going haywire. The engine would rev way too high when the clutch was pushed in and then at a stop the engine would sputter then die. I've gone to a mechanic twice and the following work has been done: first visit they replaced two gaskets..the egr valve gasket and the upper intake gasket. Well the truck no longer stalled out when stopped but the problem of the engine revving up when in neutral remained. Second visit the mechanic replaced the idle speed motor. Again it ran good..for a while then the high revving returned. Pjama - did re programming the computer at the dealership solve the revving up problem? If you can respond I'd appreciate it.
