    Misfire when warm.

    Well, got the new pump in and checked for leaks. No fuel smell and everything looks good. I'm still having a loss of power and back firing. It's not falling on its face like before but I can't get it to accelerate. I guess I'll rebuild the throttle body injection. Everything else is good. I've...

    Misfire when warm.

    I got treated with monoclonal antibodies yesterday. Last night was miserable but this morning I woke up feeling pretty good. I didn't realize how bad I felt until I didn't anymore. I figure the truck will be back together today. I bought a car a couple of weeks ago and I'd like to go get it out...

    Misfire when warm.

    I may have found the issue for my misfire. I dropped the tank and it's good and clean but the lines are eat up with rust. Since I had a pump and it was there, I replaced the pump. I also have to repair a jack leg earlier repair to the mounting strap.Repairing the lines and a new pump, it ought...

    Misfire when warm.

    Dropped the tank and put a new fuel pump in. It's the original pump so it may have been failing. I've got a bit to do before I put the tank back in. Several rusted lines and the hanger in front was a jack leg set up thta I'll have to rework. At least the tank was clean inside with no rust. Maybe...

    Misfire when warm.

    Thanks. I'll be glad when this year is over. Covid-19, I thought I sprained my foot but it turns out I broke it. Murder hornets. Monoliths appearing and disappearing. Presidential elections. My biggest fear is this year is just a warm up.

    Misfire when warm.

    My new fuel pump should be here tomorrow. If I still have issues, I'll look into that. The GF works in a nursing home and tested positive for Covid so the company sent me home to quarantine for 14 days. At least I'm getting paid for it.

    Misfire when warm.

    The timing chain was off by 2 teeth so it's been replaced. The distributor was set with my light. The old distributor was pretty rough inside so it's been replaced.

    Misfire when warm.

    As adults we often get focused and lose the sight of alternative issues. The kid has been racing go karts since he was 6. His dad and I insist he learn to wrench on his equipment. In a year or two, he's hoping to start racing dwarf cars. He's had problems with ethanol fuel rotting his fuel...

    Misfire when warm.

    Specifications for a TBI is 9-13. My pressure is fine. I was over at a friends house and was talking about it and his ELEVEN year old son asked how old the parts and truck are. It's probably the original pump so everything is 28 years old. He then said the pick up tube on the pump may be rotten...

    Misfire when warm.

    I'm thinking I have a bunch of problems. I replaced the IAC and TPS today. It idles better and doesn't miss at idle. I don't see how the old TPS functioned. I still have a stumble when accelerating. It bogs down and spits like it's not getting enough fuel. I think my fuel pump has pressure but...

    Misfire when warm.

    Well, what ever the problem is, it's getting worse. I cleaned the last of the grounds I could find today. Each ground was cleaned and reattached one by one so I know I didn't leave anything undone. Fired the truck up and got half a block before I had to turn around. It was bogging BIG time and...

    Misfire when warm.

    If it wasn't for a blip at idle, I'd think that was it. I found a kit with the IAC and throttle position sensor and a friend who still runs a shop mentioned those have a service life of 20-25 years. I'm not big on swapping parts but the shudder doesn't happen when the engine is cold, OD or not...

    Misfire when warm.

    If I dead head the pump, it might get to 18 psi but it's where it's supposed to be. I've spent a week chasing grounds and I've gotten most, if not all, of them. The radio isn't playing games anymore and my lights are brighter so the grounds needed cleaning. I still have a misfire when warm...

    Misfire when warm.

    Beating didn't do any good. I suspect a loose connection on the fuse block. I tested the fuel pump and it's supposed to run between 9 and 13 psi. A steady 11 running, static and under load. The pump is good. I started cleaning grounds. Man, there are a lot of them. Each of them so far has been...

    Misfire when warm.

    I found a rental pressure gauge kit with the adapter I need. $160 but I'll get it back when I return it. It's a 27, nearly 28 year old pump and it looks like it's been in there a while. I have another issue with the truck that I finally found a cause/effect connection. Sometimes the radio...

    Misfire when warm.

    Got off on time today and spent some time trying to track this down. I'm beginning to think it isn't ignition related. I hunted for a pressure port and couple find one. Went on Youtube to see how these are worked on and it turns out I need an adapter to get a reading. I'm suspecting a weak fuel...

    Misfire when warm.

    I've done that. I've also soaked my hand in salt water and grabbed each one. Not pleasant but it will let you know if the insulation isn't up to snuff. No ghost flashes. If it was all the time I'd say it was a bad plug. The first time it did it, it was going down the road at a steady speed.

    Misfire when warm.

    The one that was in it was pretty bad. I ordered a new distributor but didn't put it in until this all started. I got home a little early today and drove it until it started to miss under load. At idle, it's smooth. I was wondering if a plug wire was failing as the headers are VERY close to the...

    Misfire when warm.

    Short days and long work times is making this difficult to track down. I had my '93 C2500 GMC pickup singing a song but it's started misfiring when warm. When you first start it, it fires right up and runs smooth with plenty of power. As it warms up, it begins to run rough and stutters under...

    2000 Tahoe..Timing Chain Slack

    The set I put in y '93 5.7 had three key slots. There will be a note with what each one is. Unless you're souping the engine up, go the stock setting. My chain had jumped two notches. How it kept running is beyond me. It just ran rough and after running for 30 minutes, the exhaust header was 175...

    3k mike Escalade?!?!?!?!?!

    I have a friend who is gay and him and his husband told me about some REALLY persistent sites. The scammer I did it to made a lot of homophobic comments. I figure Karma could use a little help with that type of person.

    3k mike Escalade?!?!?!?!?!

    The picture look like older pictures of a dealer demonstrator. Note the label sticking out of the glove box. Those are removed when a car is prepped for delivery. If anybody wonders why scammers list vehicles cheap and want you to e-mail or call, they sell your contact information. I like to...

    Weird smell when A/C is turned on

    If anybody has ever smoked in the vehicle, the smoke particles are in the ducts and growing mold. Lysol is the first thing I try. Years ago, I got one vehicle that was so bad, people were actually getting ill from the smell. That time, I used, I think, BG Industries "Frigiclean". That required...

    2000 Cadillac Escalade. $4995

    The car is sold. Clementine has a new home. She's been sitting alone watching other cars and trucks running up and down the road. She now has a new home and come winter will be able to frolic in the snow with the other 4X4's.

    Is it possible that this Tahoe has 4WD/AWD? (pic of dash)

    I used to run a salvage yard. On an AWD vehicle, it either uses all the wheels or two of them and engages at need. It has a torque splitter, but not a transfer case. If it is 4WD, it has a high/low transfer case. I have 4WD on my 2000 Escalade. It works just like all the other 4X4 vehicles I've...
