    5.7 from 99 GMC Yukon having heat issues

    Yes I believe that's where the sending is for my coolant temp.i do have a way to check the computer so I will do that next time I get it up to that 210 mark and report back. It runs excellent so I doubt anything is wrong with the engine. It never ran this good in my Yukon lol...

    5.7 from 99 GMC Yukon having heat issues

    The radiator was built by a company that specializes in these conversions so I think it's ok. I don't currently have the ac system charged so would a helpful test be to pull the condenser? Also looking for ideas on testing the water pump. Sent from my SM-T510 using Tapatalk

    5.7 from 99 GMC Yukon having heat issues

    I do not have a shroud, I don't have the room for one. As for the water pump, it only has about 25k miles but I suppose it may be an issue. What would I be looking for? Sent from my SM-T510 using Tapatalk

    5.7 from 99 GMC Yukon having heat issues

    Ok so hear is my flood of information. I transplanted a 99 GMC Yukon 5.7 of mine into my 97 Jeep Wrangler TJ. I had the engine rebuilt while it was out but no performance changes made. Here is the current configuration. AC condenser is in front of radiator Then a 4 core radiator with left side...

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    I was hoping for something painfully obvious as I crawled under the jeep today but nothing seemed out of whack. Large and small grounds seemed ok of the ones I checked. I did notice the main 12v terminal on the starter was kind of loose. I wiggled it all around and didn't see any place it was...

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    As far as I understand they are. Someone respected on here told me it would be ok to buy 98 manuals for my 99 Yukon. Don't know if that's totally true or not

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    Yeah, I imagine so. I think I will try to check for shorts this afternoon or bad grounds and if that comes up with nothing then I will dig through. Since it was an engine swap, I know the ground points are different so it will take some digging around underneath the ol jeep. I hate working on...

    Man, it might be worth using the online tool so I can search, I forgot how thick these manuals are.

    Great advice guys!! Thank you, any replies are helpful. Is this the manual you mean? I have these if so in a box that I can get out

    I don't know anyone in my area to consult either. Anyone in Henderson/Las Vegas or know a good mechanic in that area?

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    Ugh it's been a long few weeks. I finally had to just bit the bullet and install the injectors myself. I also replaced the cat and throttle position sensor that was spazzing out occasionally. Yay, no more stink and my eyes don't burn at stop lights. Unfortunately on my 2nd time driving it since...

    I'm still fingers crossed that the mechanic/installer can warranty the labor because I really don't want to do it myself. I don't know how it compares regarding PITA factor of doing injectors on a 454 Vortec but I have done many many of those because of bad luck and continually receiving bad ones

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    Well I did get some good news today. The shop that rebuilt my engine is going to get a new acdelco mpfi unit shipped to me and they will worry about the warranty themselves later. I have moved to another state since the rebuild early this year so they are calling to see if the labor can be...

    Hey is there any other forum app that will work as an alternative to tapatalk or plans for an independent gmt400 app?

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    Hey thank you for the reply and your input! Regarding the rear o2 sensors, they have not been removed per se but have been given a static value that Black Bear felt would be good which I believe was .45v but I would need to confirm. It was about the middle of normal cycles. So no other tuning...

    Hey thanks for the reply! The fuel pressure stays totally smooth during the little stumbles. Regarding leaky injector stuff, I don't know if this indicates anything in either direction, the other day when I checked it over a period of time I forgot to take it off overnight and so the fuel...

    I have some time today to troubleshoot or get data or whatever if there are ideas on what I could check. Thanks!!

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    Oh gotcha, I misunderstood. Hey with that plug wire that arc'd/burned on the header, could it have caused a problem with the distributor cap or anything? Obviously I replaced the wire and the plugs all around are new as of yesterday but it still has that stumble at idle. None of the plugs really...

    Wow thanks for all the great info guys! I didn't know anything about the IR temperature. So I'll see if I can get another catalytic converter. I might need to order it from summit. My current one measures 2.5 in/out and is 11inches in length made by magnaflow. Should I go with that one again?

    I have not checked compression. Would the plug from a low compression cylinder look different than others on the same bank? I'm fairly certain nothing major has gone wrong. It runs awesome other than stinks and has the subtle miss. I can't imagine it would run great if something catastrophic...

    Hey I appreciate your help and sorry for the data issues. I was able to get a log file created but because its just a cheap bluetooth obd2 dongle it doesnt give much in depth access. Here are links to the 2 log files. The data is in the left sheet at the bottom of the spreadsheet and chart is...

    My 99 vortec 5.7 STINKS, has a subtle miss but no Codes or CEL

    So since I'm most concerned about the fuel trim on bank 1, I pulled all the plugs on bank 1. All plugs were dry and chocolate colored but a tiny bit lean. All wires were in good condition still. I'm also putting in a new ECT that I had. The other one seemed pretty corroded but per torque app it...
