96 GCL feels like I'm pulling dead weight!!!!!!!!!
I just bought a 96 GCL with 148,000 from a friend of the family that wanted an upgrade. She's had it since 60,000 and had regular maintance but with no hubby she just had done what the shop told her. SO a lot was overlooked.
I've already changed the plugs, wires are only a year old, 5,000 miles on tires and brakes, I greased all steering and joints, cat was recalled so that's new, but came back with a cracked header I just took it off and TIG welded it close, I'm a Machinist so I bored out the throttle body personaly while the header was off, have run lucas injector cleaner, and lucas oil stabilizer.
With all that said, it is still running a little rough at idle. Feels like its either missing a hit or the timings off. No $ right now so I have to do all the tests myself and haven't learned how to check timing yet so any hints on that is appreciated.
The biggest problem I have is that once I get to 3rd and 4th gear I have NO get-up-and-go when I hit the gas. Feels like I'm pulling a load and going up a hill at the same time. Plans to change Trans filter and fluid next paycheck.
Anybody know how to do a TransFlush with out paying a shop?
Timing is controlled by the computer, so not much you can do there. Mine misses slightly at idle also. I'm planning on doing a compression check to see if its valves. With a cracked header, you may have some valve issues.
With your no get-up-and-go I'd definitely do a compression check.
93 red ZJ 190k 4.0. Spent more money than I should have ...
Isn't red the only color a vehicle should be?
If at first you don't succeed, use more speed.
Ok, you say "its missing a hit" so I assume you are having both engine and tranny troubles from the sounds of it.
If you pin it on the highway does it kick down a gear?
When you pull the plugs was any of them noticeably different? wet or different colored? Is it an erratic idle or just a slight miss every now and then? you might want to separate the issues and work on one at a time. If it was mine I would find the root of the erratic idle first. Do a compression test, check the plugs for abnormality's and check or replace the rotor and cap if you haven't.
When I got the GCL 3 weeks ago I pulled the plugs the third cylinder, third from radiator, it was deteriated to the point that the white ceramic was being burnt back about 3/16 from original size. All others looked like normal wear. Will pull same plug tonight and see if it is any worse than the new ones now.
When goin do the highway and I punch it it does drop down a gear but still struggles. feels like it just hovers around around 2000 rpms and doesn't want to go any higher. Speed does grow but slowly.
OK, you need to do a compression test on that cylinder too. I think they rent testers at local auto stores if you don't have one. depending on the plug and what it looked like you might be running lean on that cylinder. Try unplugging that injector and running the engine. If it makes no difference whether its unplugged or plugged in you most likely have a bad injector on that cylinder. (unless the compression is too low) There is also ways to test the injector signal wires to make sure they are giving signal. 99% of the time its not the wires though, its the injector. Of course all this that i mention depends on what you find out when you do a comp test and look at the plug.
Pulled all plugs and they all look good still even though they only have 500 miles on them so not sure if any signs had time to show. Also checked distibutor and it looks bad. Rusty contacts and white build up. Cleaned up points. Seems like rotor shaft is a little lose. Able to wiggle it around in distributor. Is that normal? My truck has a coil pack so noot real familar with dist
If i has a lot of play I would replace it. They aren't supposed to flop all around in there. you probably could get a nice one at a bone yard. If you cant find one Let me know. I have an extra. build up in a dizzy is never good either. cap and rotors are pretty cheap. It just sounds like it was never maintained.
The lady I bought it from just putted around town. The longest trip she has been on in the last 4 years was 100 miles round trip!! So she just took it to the local shop for oil and tires not much else I only paid $2000 so I knew it wouldn't be perfect.
Will look into finding a replacement dist. How long do I have before there is more damage than just the cap and rotor? Prefer to find a good deal rather than just buying 1st one I find
Thanks for the help. Little ones bed time so all for today
