Thank you ALL for your help in getting this truck to pass emissions.
I put a new cat on ( Thanks TOAST) and went to the test station and it PASSED!
I am very re-leaved to get this done it has been a battle. Gary
I was taking Toasts advise and ck the ERG when the wire for #4 cyl injector came off. I cleaned the contact and put it back on. Took the truck for a spin and had no miss and it seems to me to be running perfect. I guess the miss was the loose injector wire. My next thing is to get it tested and...
VSS is in the back of the odometer and if it is not working the the ecu does not sense the speed, is that right? o2 is new. Yes some improvement but still has a miss
I am attempting to remove the bezel and spedo and am not getting very far. The right hand side will not release and I don't see how to get it out. Any body have any tips on how to do this? I have ck YouTube and don't find anything. Thanks, Gary
Hi Toast, I am about 150 south of Reno on hwy 395 in Big Pine, CA. I have fixed the splices, I cleared the code and started the engine while it was siting in front of my house. turned off the motor jumped and checked codes, no codes. I am thinking that since the speedo and odementer are not...
I found 2 butt splices and have fixed them. see photos.
The trucks runs much better but not perfect. I have the 42 code back so I am wondering how to get the harness out of the truck. Do I have to remove the throttle body and box or is there another way? I cant get to any more of the harness...
The VSS is part of the speedometer, right?
The spedo and odometer do not work, is that part of the problem?
What is an IAC?
How do you ck the injector wire harness for corrosion?
the timing chain drives the dist. so if it is jumped or loose then would it be off. at 11 deg. that is quite a bit off.
Ok, the nightmare continues. I put the truck in to the dealer and they fixed the vacuum line routing and set the TPS and timing to 5 deg. I made app to get emissions ck and on the way there it started missing. The tech at the dealer is off for another 2 months so I put it in another shop that I...
I looked under the hood and found that the mechanic had left all the hose clamps loose from air box to intake manifold so In think that is the vacuum leak the tech was telling me about during the test.
Dose anyone know what a smoke test is?
I am going to replace the cat. The tech suggested...
Sorry, it posted before I was done. The first time I took it to test they did not test it. they put the snifer in the tail pipe and it was dumping a lot of fuel out the tail pipe so I have no numbers from that test. The second time the did test it and that is what I have now so it is a place to...
New fuel pump and filter, changed oil and filter, new air filter, changed plugs , replaced missing emissions components and re routed vacuum hoses to proper placement. Had dealer set timing and TPS. put Mobil 91 gas in tank for test. Ox sensor. Truck runs good imo.
