I am capable of doing this job and I have pulled and rebuilt only one engine in the past. My current engine is in very good shape and I'm sure that all it needs is replacement of the timing chains, tensioners, rails, and guides. The chains have been rattling for a couple of months now and appear...

I now have the dreaded timing chain problem on my 1998 Explorer XLT 4x4 SOHC. I would like any input on whether I should try and rebuild my current engine or replace it with a remanufactured engine from a reputable supplier. Thanks for any input from members of this forum bfsjr

Is it possible to replace the front timing chain tensioners and guides in a 98 SOHC Explorer without pulling the engine and if so, are there any pics of this entire process. I have replaced the rear tensioners but I still have some rattle coming from the front and would rather not have to pull...

I have a 98 Explorer XLT which I've replaced the upper and lower ball joints, tie rod ends, hub/bearings, both cv axle shafts and I continue to have a whine at about 30 mph that is coming from the front. I noticed that the ATF has leaked out of the front differential on the passenger's side and...

My 93 Explorer has a bit of a rough idle and when I put it in reverse, it gets a little rougher at idle. Does this sound like a bad tranny modulator. I have no codes and there is no trans fluid in the tranny vacuum line coming off the vacuum octopus. When I take this vacuum off the octopus and...

93 Exp with KOER 157 & 998 -------------------------------------------------------------------------------- I have not repulled the codes but again today, when I started the 93 EXP it was sluggish and missing as usual with the CEL coming on, as usual. After it warmed up, the CEL went out...

I have not repulled the codes but again today, when I started the 93 EXP it was sluggish and missing as usual with the CEL coming on, as usual. After it warmed up, the CEL went out and the only unusual thing was the slight missing in the engine. You can barely feel the miss but it's there. It...

My 1993 Ford Explorer is sluggish when starting now that the weather has gotten colder and the CEL comes on and stays on until the engine gets warmed up and then the CEL will go out. Once the engine is warm, it feels like it is missing on one cylinder. I have replaced the IAC, ECT, coilpack...

I would greatly appreciate any help from you people in this forum. My 1993 Explorer XLT has been running great until the cooler weather arrived and now in the morning after a cold night, when I start it up, the CEL comes on and it idles very roughly. After it warm up, the CEL goes out and it...

Finally I think I have solved the 1993 Explorer CEL problem. After replacing the ECT sensor, the coolant temperature Sending unit, cleaning the Maf Wires, putting in a new radiator cap, a new fuel filter, cleaning the IAC valve and still seeing the CEL come on, I noticed the positive battery...

Mr. Shorty, I have gotten the code 157 every time I have run the vehicle then come back home after the cel illuminated. I extracted the 157 code in the KOEO test but I have not run the KOER tests as yet. Each time I clear the code 157, I take it for a test drive and when the cel comes on I pull...

Thanks a lot Mike for the info. I think I forgot to mention that I don't think the fuel filter has ever been changed in this vehicle. It now has 170K on it so I thinking the filter may be totally clogged thus causing the stumbles which causes to check engine to come and off. It runs okay first...

I have replaced the fuel pressure regulator, the coolant temperature sending unit, the coolant temperature sensor, fuel pump relay, and the check engine light still comes on and the code is 157 indicating low voltage regarding the mass air flow sensor. I have not yet replaced the mass air flow...

I pulled the codes and they referred me to the MAF which I cleaned and then I cleared the codes. That fixed the problem

Thanks a bunch. Will clean those things tomorrow.

My 1993 Ford Explorer stumbles occasionally and the red check engine light comes on, stays on for sometimes a short time and other times longer, and my gas guage always shows empty. I believe the float has developed a crack in the brass bulb and I plan on replacing the fuel pump and sender...

I recently added headers and a totally new exhaust system and when I tried starting the explorer it only cranked with no start. I still had it on the lifts which is where it has remained. I have checked the coil pack which checks okay but I am getting no spark at the plugs. I know the fuel pump...
