    334 code. Please help

    As far as the glowing cats. I replaced the o2 sensors, adjusted the fuel pressure (it was 50+) and adjusted the base timing to 13 (with spout out). I didn't know about the pulling the spout out thing until recently, so who knows what the timing was. I would try to set it and as everyone except...

    There is a gas smell but it's not too strong. It smelled the same way before I gutted the cats. Everything that I read pointed towards stopped up converters(as far as them glowing, it was the pre cats glowing not the big ones). They do have 230K miles on them... Another thing I have noticed is...

    Alright I am chipping away at it. I cleaned the IAC and checked the TPS. The TPS was off a little. I have an adjustable housing for the TPS. I adjusted it to .6 at idle. It was 1.5 before. At full throtttle it is about 4.7. It idles MUCH better. I have it idleing at about 1000 RPMs(this may be...

    Okay, again I sprayed enough starting fluid around the intake and all vacuum hoses to ignite a small cambodian village with NO change. I also changed the timing between like 5 and 20 with no change either. Set it back to 13. Maybe we are back to the EVR? As far as a vacuum leak I am stumped...

    Oh as far as fuel pressure it is set at 40. I can't remember what size the injectors are. It seems like they are 32lbs. I will have to find my paper work, I think it is in a file at work. Whatever they are I got the MAF to match. Timing is set to 13. Yes I installed the engine as well as built...

    334 code. Please help

    Okay, I hooked the vacuum gauge to the line going into the pcv. It seems to hold steady at 8 with light flickering most like scenerio 3 except at 8 instead of 15. however upon acceleration the gauge drops to zero and then back up. If i hold it at about 25 rpm it stays steady at 15 or so. As...

    That was at idle, and it stays at about 10 for maybe 2-4 seconds and then goes to 14 for maybe 1 sec and then drops to 8 for maybe 1 sec then back to 10. The book says it should be between 17 and 22. As far as vacuum leak I can't seem to find one. I have sprayed starting fluid spairingly on...

    334 code. Please help

    Will do. I do not have a vacuum pump thopugh. I just blocked off the line going into the EGR and went for a mild test run. It still surges. It seems like it does it an low RPMs. Also I have noticed that in between changing gears it seems like the engine doesn't idle down at all. (it's been doing...

    334 code. Please help

    Pulled the inner fender off. Something is definately hissing. The engine is so loud that I can't tell exactly what it is. Can I assume it is the EGR vacuum regulator? It is showing 30.5 ohms. That is withen the proper range is it not? Is there any other way to test this? Im getting there, just...

    334 code. Please help

    I traced it and yes it does go to thev EVR. I assume I need to test this. By reading my Haynes book I see that to test you check the resistance. It should be between 30 and 70 ohms. Is this with the connector plugged in or unplugged? I will plug line going to EGR and go for an easy test drive...

    334 code. Please help

    As far as the cats go I don't know what I will do for emissions. The old ones were stopped up. I will probably just but new ones when that time comes. Yes I cleared the codes, I think. I discon the battery for about 20 seconds or so. Took a ride and it is still surging at cruising speed. When...

    Hollowed out the cats and pre cats last night. No more glowing pipes, but I still have a 334 and it surges when driving at a constant speed.

    334 code. Please help

    Thank you, I will try this tonight. I am also going to take off the stock h pipe and make sure the pre cats and cats are not stopped up. The pre cats are what is glowing.

    334 code. Please help

    Please guys! Someone has to know a little about this stuff. I am about to pull my hair out! I have tried everything I can think of. New o2 sensors, cleaning the EGR sensor, timing, fuel pressure. Nothing works and the Ford dealership would not help me at all with any info.

    I have a 1994 Mustang. It now has a 331 with all of the emissions intact. The new engine only has about 200 miles on it and it passed emissions with flying colors. Shortly after I noticed that my cats were glowing cherry red. I haven't driven it at all since I noticed this. When I do a...
