towing after an HT383 swap??
I tow anywhere from 6,000 -10,000 lb trailers on a weekly and some times daily basis. I of course have changed to the Nv4500 5 speed, 14 bolt SF, Air Bags, 12,000 lb hitch, 10pr tires and trailer brake controller. I am still running my original L31 with 340,000 mi on it. Your biggest problem is...- 99 2dr

I got the pcm istalled today and took it for a quick drive test. The AIR and EGR readiness tests are complete, but I am now waiting on the Cat and the Evap tests to complete. Both of those tests completed just fine before so I am thinking that some more driving this evening will complete them...- 99 2dr

Black Bear did nothing wrong at all. I'll admit that I was a little nervous due to not being able to pick up the phone and call them, but Jenna was very prompt via email and altho I won't know for sure until tomorrow I think that I should be good to go. When I changed to the manual transmission...- 99 2dr

I overnighted my black box to Justin at BB. He analyzed the tune and found that the AIR system was disabled and that was most likely the reason for the AIR readiness monitor never completing. He then bench tested the pcm and the AIR and EGR monitors passed immediately. Could it be that the AIR...- 99 2dr

My headers are CARB E.O. I sent an email to BB earlier today. I wish there was a direct way to contact them. I'm starting to think that this may be the root of the problem.- 99 2dr

I Installed the new oxygen sensor in bank 1 position 1. The voltage readings Now match bank 2 sensor 1. I pulled the EGR valve, and replaced it with a new one. I had a buddy stop by with a snap on scan tool. First we preformed the drive cycle test. No luck, the air and EGR still were incomplete...- 99 2dr

I checked the flow at the valve. I will check the flow at the check valves on the headers. I re checked it and the voltage is much higher at bank 1 sensor 1 than bank 2 sensor 1. I happen to have a new set of 02 sensors that were waiting to be installed. I might stick a new one in bank 1 sensor...- 99 2dr

It would be unwise to post on the internet the things that the people in rural towns would do to the people at CARB. Ok, so this morning I fired it up dead cold. The 02 sensor readings while the Air pump was running this morning were: Bank one s1 .45 S2 .29 Bank Two s1 .19 S2 .36 Its pretty...- 99 2dr

If that were the case, then new oxygen sensors would be in order? What kind of voltage numbers should I be looking for?- 99 2dr

I pulled the valve out and verified that it is closed. I re installed the valve and started the engine with the hose that connects to the manifold check valves disconnected. Plenty of air flowed through the valve when the pump came on. I checked the hose that goes to the manifolds. There was a...- 99 2dr

I did a quick check this morning and the air pump is definitely working. Lots of suction in and lot of pressure out. How do I go about testing the Shut off valve and controlling solenoid?- 99 2dr

Well I ran it through the drive cycle this evening. No luck. Yea, Effective may 4 and I went down on the 10th for a smog test....... I will pull the hose and see if it is pushing any air. If it is moving air, where do I go from here?- 99 2dr
