Just thought I would let everyone know the update on my problems. It occassionally died on me, and overall just ran plain bad. I have changed the fuel filter, the IAC, and cleaned all the areas that were recommended in the tech section. I happened to find my number 7 spark plug wire almost completely burned into at the distributor cap! How did the dealer miss that??? I replaced the wire, and I have ordered new a set of new ones. I reset the check engine light after replacing the IAC, it lasted about 300 miles before it came back on (it always comes on at idle). It throws code 44. Could a bad O2 sensor cause it to run that bad? It seems to run much better when it is cooler, and horrible when it gets hot. I am still thinking Ignition Amplifier. I will let you know the outcome. | ||

As the pirates used to say, when you hit treasure, stop digging. Don't do anything until after you replace your plug wires, cap and rotor (when did you last change plugs?) You KNOW you have bad plug wires, change those and then, if you still have problems, you can start thinking about your Ignition Amplifier. Jim | ||

Sounds like a plan...I am going to change the wires, cap and rotor out this weekend, along with a set of fresh plugs. I hope one of those does the trick. I am also running some Sea Foam through it, since people on this board all seem to agree that it works pretty well. Thanks for the input. | ||

mark, i had a similar error, after lighting up my wallet it turned out to be a bad non oem cap. be sure to get one from LR. imho mike w | ||

Thanks Mike, I will be sure and do that. The OEM cap should say Lucas on it?? | ||

I was getting rough idle and code 44's on my 95 disco, I replaced the O2 sensors and my disco is running like a champ again. I'm not saying that it'll solve your problem, just giving my .02 cents. wes | ||

Howzit Mark. I think that you might have two problems. The first one might be the codes you are reading....Oxygen sensors...I think it means that you are getting an imbalance in your air/fuel/ and firing readings to the computer, which puts out the codes. There seems to be quite a few sensors and other things that are related to that code. The second problem might be that since you said that your car runs better whan it's cold, it could be a stuck thermostat, that could mess up a good day here in Hawaii. I know that one. Or maybe that cars that now have computers to run the systems run on a "open loop" , and everything runs OK until the vehicle reaches operating temp. I just bought a Haynes techbook on computer codes, so now I know that these cars run ok 'till they warm up and start firing out codes. I'm only to chapter 4....so If I get any new positive insight to share...I'll post it here. Aloha, Lou | ||

mark, can't remember if lucas is part of the cast but the oem unit is blue. get the rotor button replaced as well. mike w | ||

You bring up an interesting question...I wondered myself it the code 44 error was actually a result of something else going on with either the ignition or fuel delivery. Hopefully doing the ignition tune up this weekend will shed some light on the problem. I love this vehicle, I just want to make it reliable. Thanks to all for the help. | ||

Code 44 - Lambda sensor A - left bank Code 45 - Lambda sensor B - right bank how's the gas mileage? mike w | ||

Here's a pic of a new O2 sensor and an old one. The old one came off of my 95 disco with 98k mi.  | ||

Gas mileage seems pretty poor...also, sometimes I swear I get a strong odor of raw gas...but it doesn't seem to have any rhyme or reason. Did you replace the O2 sensor with OEM LR? | ||

I find the blue distributor caps to fit the distributor too loosely and as a result the cap floats around on the distributor and the timing changes constantly. I have gone completely to NAPA ignition components on my and my clients trucks and have not had an ignition related return yet. The blue caps can be made by interparts. Most if not all of the OEM caps I have ever seen were black. | ||

Mark, Got the O2 sensors from Nathan @ Discount Rovers. www.discountrovers.com | ||

I had the exact same problem. After cleaning the MAF and replacing the (can't remember the name)vacuum part at the front of the engine with a hose running to the top of engine, the truck runs great. 95 D1 Codes read 44/45 but are now clear and I didn't replace them. | ||

i had a new black cap on my truck and itwent south on me a few months after i placed it on the truck. now in all truth this failure came about after the failure of one of the plug wires. the blue cap does fit a lil loose but jumping timing, hmmmm interesting thought but i never that experence before nor have i seen it now. nathan will sale you a good O2 sensor. mike w | ||
| Mark McLain (Mtndisco) New Member Username: Mtndisco Post Number: 16 Registered: 05-2003 |
James Did you just clean the "T" vacuum section that goes to the manifold, along with all of the hoses, or did you do a more extensive cleaning than that? I would like to try that since it worked for you and hopefully I won't need to order that O2 sensor...hopefully...  | ||

Anyone have the part # for the NAPA replacement distributor cap? | ||

UPDATE!!! Ok, here is some additional information for those trying to diagnose my problem. This morning, I was reading about someone who disconnected their IAC and said that it improved how their D1 ran. So, on my way to the dump this morning, I disconnected mine. Here is what happened, it actually sat there and reved on its own, from about 1100 rmps up to 1600. It just sits there and revs. If I put it in gear and drive, the revving stops, but at idle, it continues to sit there and rev (quite quickly actually). Any ideas appreciated. | ||

mark, there comes a time when a fella just has to recoginize his limits. imho its time to take that dreaded, shameful trip to the dealership. theres nothing there that you couldn't do yourself, they just have all the tools. mike w | ||
| Mark McLain (Mtndisco) New Member Username: Mtndisco Post Number: 20 Registered: 05-2003 |
M.K., I completely understand...except that I did take it to the dealer, and after 3 days, they could not get it to stall, etc. They were ready to just start throwing parts at it... | ||
| M. K. Watson (Lrover94) Senior Member Username: Lrover94 Post Number: 885 Registered: 02-2002 |
got ya! well in that case re-write your dairy, listing all the alements and what you have done to correct it. see how it all links together.(writing it all down helps the thinking processes) it sucks throwing parts on and not coming up with an answer. the dairy keeps you from repeating your previous failures. these are just machines, there is no real mystery just issues and corrections. mike w | ||
| Mark McLain (Mtndisco) New Member Username: Mtndisco Post Number: 21 Registered: 05-2003 |
Attention Paul: I seek your wisdom on the possible causes of this recent discovery...namely the revving with the IAC disconnected...Oh please, master of the Rover, enlighten me! |
