We have eliminated it now, except there is a very small trace of it remaining. Problem just showed up one day, no definite reason ever found. We have a 30' 2001 Itasca Sunrise with the 7.4l gas workhorse chassis. We went through the same thing (needing to two foot through towns with stop lights while on long drives). :( Not exactly what I'm wanting to hear, ya know? )Īnyway, any advice you might have would help tremendously.ĭid we ever here if Steve got to the root of his problem? The first mechanic thinks it might be related to the EMC as they unplugged a couple of sensors and said the computer didn't throw any codes.Īny other thoughts? And if it is possibly the EMC, how does one get it tested and/or replaced? I can't find information online about it, and the mechanic claims he called around with a part number Workhorse gave him and couldn't find a replacement computer anywhere. So far, we have replaced all the plugs and wires at one mechanic, had another convince me it was a bad tank of gas, so changed the fuel filter and put fresh gas and additive in, but the problems still remain. And as soon as I came to a stop, if I didn't "two foot" it again, it would stall. It would run ok once I got up to speed, but acceleration was pitiful and it still felt a little rough. After that, it would stall at idle, and I would have to give it gas to stay running, then "two foot" (one on the brake, one revving the engine) to put it in gear and pull away. A couple months ago (we've been relatively stationary since, trying to solve this problem so we can continue traveling), pulled up to a stop sign after an uneventful 2-hour drive, and the engine stalled. Any help would be greatly appreciatedĢ005 Damon Intruder on a Workhorse chassis with the Chevy 8-cyl engine. I notice the spark plug wires were changed twice at 1400 mile because of cyl 5 and 6 wires were bad. I have checked at the throttle body and the Tac for broken wires by pulling each wire and doing the wiggle test while it is running but no luck in having it fail vin # 5B4MP67G733364685 The motor home has 18530 miles and I have all the inspection papers and work done. Before I go and start throwing a lot of parts at it what would you suggest.
#SNAP ON MODIS ULTRA TURN OFF SEET BELT CHIME CODE#
I have a code reader and the codes were P1516 and P0151. I stopped on the side of the road for about 10 minutes with the motor off and it started right back up and ran like nothing happened plenty of power no miss. I started the motor and it ran very rough and could not go more than 10-15 miles an hour. The next several days started right up in the driveway and we went to have the propane tank filled and were on the road for about an hour cut the motor off and it took about 20 minutes to fill the tank. I stopped on the side of the road for about 5-10minutes with the motor off and it restarted just fine and no miss and plenty of power. I stopped and filled the tank and it started running rough and would not do over 10-15 miles an hr. I drove it 2hr after pickup and it ran fine plenty of power. Hello Alan, I purchased a 2003 Winnebago Adventurer 35U workhorse chassis 8.1. We are getting no help from the RV dealers in the area.
I have looked for evidence of rodents, but found none. The rig is a 2002 and only has 4750 mikes on it. There is very limited throttle response, maybe from 800 RPM to 1600 RPM, with the throttle wide open. The PCM is getting no info from the module, but cannot determine if the module isn't sending, or if the PCM isn't recognizing and processing it. I have been attempting to use a diagram from the same year 3500 Van with the 8.1, but am struggling with which "orange/Black, cir. I am trying to check the Data lines from the TAC to the PCM, but cannot verify which ones at the PCM are the proper wires. Nothing seems to help, but we can return the pedal and t-body.
Replace the throttle pedal, no change, tried a new t-body, nope, then the TAC module itself. Without a wiring diagram its tough to diag, so did the next best thing.throw parts at it.
They flew back to Wisconson, and left the rig with us. It was late on a Friday, and I really have no info on that chassis, so they were going to try a local RV dealer, but got little response. I scanned for codes, and got the dreaded P1518. The tech there cleaned the T-body, and it seemed good, until they got back on the interstate, where they limped it to our shop. They made it to our sister shop in Gainesville, Florida, and the rig went into " reduced power" mode, with no throttle response. The owners were heading home to Wisconson in this rig they had purchased at a small "Mom and Pop" car lot in Ocala, Florida.
I am working on a 2002 Workhorse W22, 8.1.
