  1. Hey gang, I went for a smog test and they said that my RV is missing the "back pressure modulator" which I've come to learn is also called the "vacuum modulator." I had the shop that did the test do the repairs, which I'm not sure was a great idea. They said they ordered the part but what they got doesn't fit bc they need something like the part pictured but with only 2 ports (1 on each side) rather than the 2+1 in the picture. But they can't seem to find one like that. What little I've found online suggests that the right part is a 2+1 like in the picture. For example, this one on eBay which claims to fit "22R 81-88," or this other one on eBay which says it fits "81 to 83 Toyota Hilux Pickup." Is the shop wrong? Or am I missing something? As always, your help is greatly appreciated. Thanks, Lenny
  2. I recently purchased a 1986 Travel Master and noticed a faint smell of gasoline in the cab while driving the other day. Once I was home I checked to make sure the gas cap was good and for any noticeable leaks and didn't see any, but I noticed a pretty strong smell of gas coming out of the exhaust pipe. What could be causing this? Does it require immediate attention or am I okay to drive?
  3. Hello! This is my first post. We have a 78 micro mini with a 20r engine. I just had some exhaust work done but the guy was trying to charge me a bunch because he thought j was crazy. I read that people were running 2.5" exhaust and it was working well for them. He wouldn't do what I want for less than 600 so I just had him run 2.5" from my headers that I put on to a 2.5" converter. Then reduce down to my original exhaust. I know it's not perfect but I will finish with a 2.5 muffler and tailpipe soon. While it was idling yesterday I pulled of the air filter. It was idling very high. When I removed the filter it went down to a comfortable idle. Could this be timing or fuel/air mix or would an after market air filter work for the new exhaust. Also any suggestions on air filters. Thanks guys!
  4. my first post! (and most probably not my last!)..here's my situation: 1993, 21' Conquest, 53,000 miles, third owner - bought from a friend of a friend last fall. Sold off house and all my belongings and hit the road to full time it in January...yep escaped most of those 'polar vortexes' of last winter - and have had some trials and tribulations that would be expected driving a 20 yro vehicle..that is actually in pretty darn good shape... had the truck 'once overed' before i hit the road and replaced all the hoses etc... i am not a mechanic at all, but have a few friends who are real motorheads and for the most part anyone who stuck their head under the hood all said the same thing...what a great little engine (V6), well maintained and all good...(lucky me!!) now for my problem: while in the san antonio area last march i decided to have the tail pipe and muffler replaced (didn't like the sound the exhaust was making - though it had passed new york states emissions for inspection a couple months earlier)..brought it to ahem, a nationwide chain, and yes they had to do a little extra on the tailpipe - but managed to replace the muffler and tailpipe..i drove away liking the new purring sound of my new exhaust. about 50 miles west of san antonio (heading out to big bend..btw...highly recommend this remote national park!) i notice the floor boards in cab getting hot..i mean HOT..could feel the heat coming through my shoes! pull over and as i am getting out of the vehicle it was like stepping through a sauna of HOT HOT air just outside the drivers door. the hood of the engine? WAY HOT to the touch: btw the temperature gauge showed the internal temp of the engine to be perfectly fine. there was also no noticeable change in the way the rv was driving...just really hot. had a local mechanic take a look see (mostly because i was petrified the whole thing was just going to go up in flames at any given moment) he determined the cat converter was needing replacement, and assured me as long as i pulled over and let the whole thing cool down once in a while i would be able to safely get back to san antonio..aka 'civilization'..which i did: brought the rig back to the AHEM, national chain, to replace the catalytic converter (all pretty costly - but hey...this is my HOME now!). at the time i thought it coincidental that right after they replaced the tail pipe and muffler (and had obviously checked the cat converter which was fine) the cc went on me..but okay..lets move on...next day i find out have to get back to long island pronto...head out on the road in a new york state of mind...this is early may and the weather was warming up. the ride back was brutal...outside the wildflowers were blooming and all was well with the world..but inside the vehicle it was still HOT HOT HOT (again, not only a bit concerned with safety issues...but, me and my two labs were miserable...yeah, i could keep the A/C on directed at the floorboards all the way home from texas...but my mileage which seems to be no where near as good as everyone else's on this forum (i will post that another day) drops even lower with that a/c going...so windows open..nearly naked, and two panting labs ... we got back safely... have had several different mechanics look at this issue from the local shop of the 'nationwide chain' who told me this had nothing to do with the exhaust (hmmm..even though it all seemed to happen right after the tail pipe and muffler were replaced)..and that my engine was running lean...to a transmission guy (btw...not overweight...had the rig weighed, and though i am just about at GVWR...i am NOT overweight (like my new lifestyle of less is more!! - plus i think driving in this ^%$&* sauna has even made ME lose some pounds!))...transmission guy installed the largest aftermarket cooler he could fit in (umm, yeah at new york hourly rates)...then desperate...i turned to toyota dealership (ny dealership hourly rates...ugh)..they actually were pretty helpful...and determined that yes, engine running 'lean' due to 02 sensor located on downpipe leading from engine right before cat converter...downpipe has small cracks in it (yeah, its old and probably got cracked up when lugheads were working on exhaust down in texas)...heat escaping from cracks, 02 sensor making engine run lean, all heating up...seriously heating up...here's my dilemma: they couldn't find a pipe to replace my cracked up one (the service guy at dealership fell in love with my rig and sincerely trying to help me...way beyond normal dealership service...again, lucky me!)...decided to try to buy me some years of driving by using some sort of special nascar high heat wrap..and basically wrapped up my cracked downpipe to stop the exhaust leaks and prevent the 02 sensor from messing up my fuel ratio...okey dokey:...well maybe it helped, but not really...i am at a loss??? the heat shields are all in place and are in good shape..don't even know if this is an exhaust issue or not (just know that the problem arose right after the initial tailpipe/muffler replacement)...has anyone else had anything like this happen? please help me...i love my new nomadic life in my little ole' toyota (and so do the dogs)...and i am just about finished with my long island stay and am itching to get back out on the road...but not if it means at the worst having my rig on fire on the side of the road (the engine reads around 385 degrees (externally) after driving for about a half hour..) or at best, having to drive with panting dogs and me naked...oh, and the best part: i originally had the tailpipe and muffler replaced because i didn't like the rumble sound from the exhaust...sounded too...i don't know, masculine, but now, because of all of this heat whatever 'insulation' or whatever that is in the exhaust has been 'burned out...my nice purring exhaust sound is back to that offensive rumbly sound....UGH!!!
