misfire

I have a 1988 bronco 2 and it is running really weird, it idles not to bad in park but there is still a misfire but as soon as I put it into drive it bogs down doesn't like to go it sputters when I press on the gas and if I stop at a stop sign or street light it dies. I took it to a shop and...

New member to this site but I've been using it since I was 15. Finally got smart and became a member...11 Rangers later. I just picked up a 99 Ranger XLT 2.5L auto 2wd with 158k miles. Bought it running REALLY ROUGH and drove it over an hour back home. Seems like it's running on 2 cyl's. Can't...

I have a 1998 ford ranger xlt with the 3.0 and its 2wd with 185,000 miles on it. For the past 2 months its been bucking while I drive and its lost performance and sounds like i have a misfire. It only bucks when i accelerate or when i stay at a constant speed over 40. I have checked for low...

my 1999 ranger has the 4.0 liter v6 and 4 wheel drive. my truck has presented the cylinder 6 misfire code twice in the last 6 months, which I have fixed with a new spark plug in that cylinder. The other day, however, it started stuttering heavily under load, and all of the sudden had very little...

I know "loss of power" has been answered before, (and believe my I've searched) but I feel my situation is unique. As soon as my 302 swapped Ranger was driveable, it ran great. The slightest tap of the gas pedal would roast the tires (or tire, with the stock 93 open differential haha). About a...

I have a 1994 ranger 4.0l 4x4 stx So one day I was out on the trail and my truck was running fine, shut it down, and it wouldn't start. The fuel pump was going bad so I was expecting this to happen anyways Buy this is when my problems start. I replace the pump and filter and the truck is running...

So i have a 1999 Ranger Supercab, 4x4 with a 4.0 and a 5 speed. A few months ago it started stuttering when cold, when i would accelerate, but would go away after 5 or so minutes of driving, and often less than that when i would floor it. Yesterday, however, it started stuttering more often...

Hello everyone, new to this forum. I searched a bit but couldn't find anything that addressed my issue directly. 1997 Ranger with 2.3, 2wd, 5 speed manual, everything is stock, no aftermarket pieces. Bought the truck and had an intermittent misfire code on cyl 2. Finally tore into the engine...

Hey everyone, This is one of my first posts, but i've been lurking for a while. Just got a 94 4x4 4.0L V6 Manual with 225k. engine runs strong, however, There is a moderate leak in the passenger side valve cover. While coming out of a stop into 1st gear today, the engine suddenly lost...

First off would like to start and say thanks for all the help with my previous thread a few months back. I got the problem worked out, turns out it was a "weak" fuel pump. Anyhow while driving today to get a part for A DIFFERENT vehicle, which is broken down, I hit a hug hole, open manhole...

Hello, I drive a 1998 Ford Ranger XLT 3.0 v6, manual with 236k miles. replaced the head gasket, timing chain, and cracked timing chain cover and spark plugs 2 months ago(about 5k miles ago) Aside from my slave cylinder and clutch beginning to go bad I haven't had any problems since, until my...

93 3.0 This has me stumped. I have fresh ignition everything. Plugs, wires, coil, distributor cap etc. It doesnt always do it but if i keep it at steady throttle around 1500-1600 RPMs it acts like it has a misfire. Any more or any less throttle and its fine. Ive sea foamed it and that worked but...

I own a 2004 Mazda B3000and I'm having a good bit of trouble figuring out why I have a weak spark out of my first coil on the module and good spark on the other two. I have replaced the coil three times, replaced plugs and wires and fuel filter. The truck wont even spin a tire in gravel. No...

A few weeks ago my CEL came on, showing a misfire on cylinder 3. The truck still drives alright, but there is noticeable shaking at idle and at about 1700 rpm. My mileage has also dropped off pretty suddenly. I switched plug wires, got new plugs, made sure spark was getting to the plugs, and...

Hey everybody, really been enjoying reading all the information here. I bought a lovely 2001 3.0L XLT with flare sides about a year ago and our relationship has been on the rocks for the past few weeks. I'm getting conflicting signals and not sure really what's going on. I'm having rough...

I have searched multiple threads and the ones that seem promising, stop without the end solution. I have a 1996 4.0 and have had multiple issues trying to get it to smog. I have replaced an o2 sensor, spark plugs and spark plug wires. After this, truck was running fine and then a code got thrown...

Misfire on cylinder 5 p0305 (problem solved) Ok i have an issue, I have an 2004 4.0l and i have two codes that just showed up today. p0305 and p0316 since then I have replace the coil-pack, plug wires and plugs. I currently don't have access to get cylinder pressures or preform a leak...

I have I 99 B4000 M/T, flowmaster muffler, magnaflow cat, K&N FIPK II intake. My engine is lacking power throughout the rev range but is most notable on the highway. I have trouble maintaining 65 if there is even the slightest hill, which usually requires downshifting and putting it to the...
