colinchaffers Posted September 6, 2018 Share Posted September 6, 2018 I have a 3 year old Ranger 3.2l. (The latest version). Over it's life I have a occasionally had a problem on start up (only) where the idle speed becomes erratic and the engine cuts out. I have to leave it for 10 minutes and it normally clears itself. Ford have not been able to find the problem. But I don't think I can be the only customer with this problem.

transam Posted September 6, 2018 Share Posted September 6, 2018 Get it sorted whilst still on warranty. If they cannot get onto head office.. Link to comment Share on other sites More sharing options...
cornishcarlos Posted September 6, 2018 Share Posted September 6, 2018 The problem with erratic faults is the garage (not just Ford) will often say they fixed it, but then few weeks later you have the same issue. Hard to diagnose and rectify sometimes but instead of saying that, they will often just say they fixed it (that face thing)... 1 Link to comment Share on other sites More sharing options...
HAKAPALITA Posted September 6, 2018 Share Posted September 6, 2018 Anyone remember the era when all Euro Fords had starter motors that made you go Jesus.!!. whilst all the others sounde normal. about Sierra era perhaps. They soon fixed that. Link to comment Share on other sites More sharing options...
NanLaew Posted September 6, 2018 Share Posted September 6, 2018 ...or try another dealership? Definitely a warranty job and at 3-years, that must be closer to expiration? I the OP hasn't left the truck with them for a few days so they can 'catch' this occasional problem, maybe that has to be an option although a bit inconvenient. I hope the OP isn' in Phuket thought since last I read, all their dealerships there are caga. Link to comment Share on other sites More sharing options...

I hope the OP isn' in Phuket thought since last I read, all their dealerships there are caga. The real issue is that the problem once clear does not happen for two or three months, Ford has had the car twice for "a few days", but once they checked the diagnostic system and could not find the problem they cant do anything else. I suspect I'm not the only one with the problem hence my post. Link to comment Share on other sites More sharing options...

Lacessit Posted September 7, 2018 Share Posted September 7, 2018 The OP should be able to check various online customer sites to see if other people are having the same problem. If that's the case, he should approach the manufacturer directly. Dealerships around the world hate warranty claims, because it comes off their bottom line. 1 Link to comment Share on other sites More sharing options...

Jeffrey346 Posted September 7, 2018 Share Posted September 7, 2018 I had the same problem with my Vigo. Toyota plugged in the diagnostics and said 2 nozzles are partially clogged and need to be replaced at B10,000 each. I called the local shop I use and was told to buy Liqui Molly Flush B750. Pour it in the tank, fill the tank half way with Shell V-Power, run it to almost empty. He said this should clean all the injectors and nozzles. He was correct the problem went away. You can buy Liqui Molly on Lazada. For B750 it's worth a try. 2 Link to comment Share on other sites More sharing options...

yrag Posted September 7, 2018 Share Posted September 7, 2018 You might also want to do a soft reset.....turn key off then on......disconnect negative at battery for 5 to 10 minute .....with key still on connect cable on battery....then turn key off then back on and or start.... 1 Link to comment Share on other sites More sharing options...

A similar strategy was recommended to me by a mechanic for my Vios. Rough idling. Disconnect negative at battery for 30 seconds. Reconnect. Has worked every time, apparently it resets a computer chip. 1 Link to comment Share on other sites More sharing options...

But I suspect the problem is related to timing and or software. Sent from my SM-G935F using Thailand Forum - Thaivisa mobile app Link to comment Share on other sites More sharing options...

Foexie Posted September 7, 2018 Share Posted September 7, 2018 Better ask your question on a Ford Ranger Forum. There are several. So if it occurs to more they will have the answer and solution for you. Link to comment Share on other sites More sharing options...

It’s a Ford, he’s lucky it starts at all. Had the same situation a few years ago with a Ford. They stuck a sensor recorder in the electrical system to trace and record malfunctioning systems. Had it in for a week and despite the problem happening about 10 times, it didn’t pick up any faults! Needless to say, we got shot of the heap of shit ASAP. ?
