Ford 7.3L Power Stroke (1999-2003) :: F250 Surging - Running Rough - Dies?
I have a 99 f-250 with about 250k miles. Truck is completely stock. It recently has developed a problem where when I start it in the mornings it surges at idle, 200 rpm or so. Sometimes it tries to die and did once but started back up. When driving it continues to rev itself up and is jerky. It runs rough and sounds like it could be missing on a cylinder. At other times it runs fine just like normal. Yesterday morning it started with these symptoms so I put in a new ford CPS. It ran great for about 100 miles that afternoon. This morning it started back with the same symptoms. The SES light stayed on longer than normal when I started it, but it went off. I don't have a scanner.
I thought it might be water in the fuel because this started the day after I filled it from my transfer tank. But the water in fuel light has never came on. I put a new fuel filter on it but it made no difference. Have pulled filter three times looking for water but never found a drop. Also pulled several buckets from the bottom of my transfer tank but found no water there either. Where to look next?
Sierra :: 4.3L Running Rough When Cold - Engine Is Missing
We have been having issues with my son's 97 Sierra running rough when it is cold/damp. It feels like the engine is missing.
Today, which is warm and dry, it started running really bad and it was all he could do to limp it home. It seemed like it wanted to idle fine but when he tried to rev it up the tach would start jumping and it seemed like it was missing.
Could this be a bad cap/rotor? The engine has 200,000 miles and we've never changed the cap/rotor. I changed the plugs/wires probably 100,000 miles ago.
Passat (B6) :: Running Rough / Surging When In Drive And Stopped
Had the oil changed yesterday and changed the air filter myself. Car is now running rough, surging, when in drive and stopped. Runs cleanly when moving and surge is significantly less in park and neutral.
View 3 RepliesFord Fuel System :: Running Rough - Skipping / Surging And Die
I built the 400 in my 79 a couple years ago and it runs very well...until yesterday. I'm about 80 miles into this tank, and on my way home from work, I thought I felt a vibration (not in the steering wheel, but in the front oc the truck). Then the engine became evident it was running rough and was skipping and surging. I stopped.
It idled pretty rough, then died. Fired right back up, ran rough, and died. Sometimes it would idle smooth for several seconds (20-30) then start surging and skipping and die. I could hold a little throttle and it would run about the same, except some backfiring in the exhaust (more like a big hiccup).
The carb is a 670 Street Avenger with nothing really done to it. The bores are really black (not sooty, more damp or so). I have always used the air filter, so that's odd. I took the carb off and removed the bowls. Nothing inside has a dirty or clogged appearance at all. Not sure if I should completely rebuild it.
Sierra :: 1990 GMC 4.3L - When Warms Up It Starts Running Rough Then Stalls And Won't Start
My fathers 1990 GMC Sierra 1500 Pickup Truck 4.3L runs fine when it is cold but as soon as it warms up it starts running rough then stalls and won't start. There is no spark when it dies. As soon as it cools off it starts back up and runs fine till it warms back up.

I live in Kansas and was home in Georgia for the last 2 weeks. The truck drove great there after a fuel up started missing and surging at 50 to 70 thought it might have been bad fuel. waited till it was low added Lucas fuel treatment and premium gas still was doing it. no check engine light. went to Advance and fuse for light was blown they checked and was getting mass air flow code. unplugged it and seemed to be better, not perfect but better. plugged it back in and went to do it again. Changed mass air flow night before the drive back to Kansas. Ran well from Savannah to north Georgia then started doing it again the rest of the way home. Going to have advance check code again.

View 5 RepliesFord Aerostar :: 1994 Starts / Idles About 10 Seconds Then Begins To Idle Rough And Dies
I just replaced the water pump and put it all back together, now it won't run well enough to drive. Checked vacuum system, all sensor connections, hoses, gas cap, changed fuel filter, I can hear the fuel pump kick in, reset system with battery disconnected and have looked at everything I can think of so far.
Now - starts fine, idles about 10 seconds and then begins to idle rough and dies. If I use the throttle I can often keep the idle up, but then backfires or acts like no fuel and again dies. Used fuel cleaner and made sure there was plenty fuel in tank.
I am looking at replacing sensors at this point but which one first?? They get a bit expensive real quick.
Ford Ranger / B-Series :: 1994 - Running Rough At Idle?
Engine runs rough at idle. Two plugs are black and just replaced head gaskets. I installed new short block and new heads six months ago. I can't seem to figure out the problem and I would like to trouble shoot more before tearing heads off and going any further.
View 2 RepliesCamry :: 2005 - Running Rough And Dies Without Foot On Accelerator
So I have a 2005 Camry XLE, 3.0 l V6 with 160k miles. The car was running fine, but I decided to change the spark plugs today (overdue).
I went through the headache of removing the intake manifold, throttle body etc and everything seemed to go OK. I reassembled it all and now it won't idle properly.
It seems like a vacuum leak issue to me, but I have double checked the multiple hose connections. I did NOT disconnect the battery at any time.
I can Rev it up to 3 or 4000 rpm and it runs smoothly (all the cylinders seem to be firing) but it runs rough and dies without my foot on the accelerator. Also I noticed the exhaust manifold got cherry red like right now... after only a minute or two of running.
Are there any troubleshooting checks I can perform to narrow down the source of the vacuum leak?
Honda - Accord :: Check Engine Light On - Engine Surging / Running Very Rough
My mechanic tells me I need the intake manifold gasket replaced (check engine light on, engine surging, running very rough). How much damage can I do to the car by doing this repair myself and screwing it up? I've done lots of repairs on my car before -- brake pads, rotors, replace oil pan. I also have a copy of the manufacturer's shop manual.

This truck has 180km on it and runs fine except as of lately i have developed a surge while at constant speed. When i step on the gas it does not seem to happen.....it only happens when I reach a constant speed. The odd time it will surge at idle and the engine will rev up and down on its own also. When at highway speed it seems to not do this. The truck never dies completely....just surges slightly.

My wife's 06 expedition 5.43v runs rough loud and dies. Not all the time just when it's to hot. I got a code it's p0022 cam sensor. I changed both started the rig up and heard loud rattling like metal maybe chain. It lasted for a the length of my video 1.4mins give or take then went fine, i turned the car off and back on everything seems fine. I know I got her oil done after driving. She had metal/plastic in her oil. I had all plugs done and actually i re did the 8th cylinder plug because it was miss firing and i pulled it by hand with only the socket no ratchet. I'm thinking the chain is going bad if not already bad. Only 113k miles my 04 f150 5.43v lasted 250k before motor swap...
View 7 RepliesBuick - Lesabre :: 1994 - Custom Diagnostic Cannot Connect To Or Read ECU / Intermittent Stalling / Rough Running
I have a 94 buick lesabre custom that is stalling intermittently and runs rough intermittently. We have had it for diagnostics and it could not read the codes. We changed the computer and it still can't read the codes. The diagnostic tool says it cannot connect when it is plugged in or it displays white flecks like snow flakes on the tool screen. It is an OBDII. The pin structure of the data connector port is two pins top row and bottom row two pins some blanks and one pin. We don't know how to fix it with no diagnostic codes and we don't know what to do to get the codes because we have changed the computer.
View 8 RepliesGMC - Sierra :: 1994 - Tuning Up - What To Change
I have a 94' sierra with a 350 cubic inch TBI. I've already replaced the thermostat, spark plugs, clutch and had the oil changed. when I bought it it looked like the plug wires and distributor cap had already been replaced recently. the big question is, other than replacing the air filter (which doesn't look like its in to bad of shape) what else should I look at doing to tune it up a bit? this is my daily driver/work/scrap hauling truck so I want to keep it running well and for a long time. there was a small metal hose that ran from my intake to the heat shield around my exhaust that got mangled pretty bad and just removed, what was it for and is it worth the expense to replace it? also I've seen ads for throttle body spacers, are they worth it? and would I need to make any changes to the ECU at all if I put one on or even put performance headers on it?
View 13 Replies4Runner/GX470 :: 1994 V6 - Hesitation And Surging / No Power
My 94 4Runner V6 has been acting up for over 4 months now. I've replaced the mass air flow sensor, the fuel pump, the fuel regulator, the O2 sensor, the spark plugs, spark plug wires, new distributor and rotor and last but not least the fuel line filter and dam it it's still screwed up. The spark plugs didn't show any signs of sooting or fouling in any way, I compared there color to Other used spark plugs and they looked good.
I've spent over $2000 on this 4Runner that had run perfect for almost 14 years and now I cannot even drive for 5 minutes without it bucking, hesitating, with No Power at all and eventually stalling. I also replaced the ECM or ECU with a good used one. I also cleaned the air intake and throttle body and cleaned and reattached the ground to the battery, the ECM, the coil which shows as being good, the ground to the engine from the firewall were also inspected and cleaned. I even bought a new gas cap for the gas tank and also had the fuel injectors cleaned at the dealer and "They Said The Engine Runs Perfect When It Is Hooked Up To The Fuel Injector Cleaner" but when it's hooked up to the fuel system again it acts up again.
One Thing About It IS When It's Acting Up If I Turn Off The Engine, While In Neutral And Restart It It Works Good For A Few Minutes Then Starts Acting Up Again. The engine is good, there are times it works Perfect for a few hours but Eventually it will act up.
Now that the summer is on us it's acting up even more because of using the air conditioning. It use to only act up when it would be warmed up or hot and only when there is a load on the engine, like driving around normally, but now it's even acting up when it's idling after just starting it.
Gmc - Sierra :: 1994 - Driver Side Track On The Bottom Of The Window Rusted Out?
The driver side track on the bottom of the window has rusted out on my 1994 GMC Sierra pickup. Every place I've talked to that is supposed to handle glass repairs either doesn't fix this kind of thing or just plain doesn't want to attempt to fix it. The only advice one place would offer is to buy a new window with a good track on it, but how to get the old one out without breaking it or putting a new one in. I know they sell just the track for these windows, but I don't know how to remove the old one without breaking the glass.
View 24 RepliesFord Ranger / B-Series :: 1994 3.0 4x4 - No Start / Surging Idle When Hot?
I'm having trouble with my ford ranger. It cold starts fine, and drives fine while cold. Once it warms up the idle is barely keeping it running, or surging 1000-1500 rpms above normal idle. Any gas I apply while hot idling will stall out the motor, and will not restart. It acts like it is very flooded when I try to do a hot start. I pulled the IAC valve off and cleaned it even though it was very clean and actuated properly. I also cleaned my MAF, and that changed nothing. I really do not want to just throw parts at it hoping I guess right before I'm broke. Not sure where to go from here, and I live in Alaska where I am fixing this outside.
View 1 RepliesSierra :: 02 Dies As Idle Drops When Slow Down To Park Or At A Stop Sign
I got a 2002 sierra 1500 with a 5.3l. I just replaced both catalytic converters and y pipe. After I did this, I am having a few problems. First, when slow down to park or at a stop sign the idle drops way down and it dies. I cleaned the throttle body, maf sensor, and ran a can of seafoam and a can of b12 chemtool through it. It did this for a couple of days and now when the idle slows down the "check oil pressure" light comes on before it dies. Then yesterday the "check oil level" light started coming on. Is this all related, would the low idle cause low oil pressure, where to start?
