There is a "throttle valve" cable located on the throttle linkage of the carburetor that may have been reset or left unhooked when you had it serviced. Check to make sure it is connected to the throttle link.
Also behind the carburetor there is a vacuum line connected to the intake manifold that goes to the transmission vacuum modulator, they may have knocked it loose or the hose cracked.
Check it out and let me know.
Regards,

How to Replace a Distributor Cap in Toyota?


Its a plastic cap and and on its top the sparks wires get connected.A small plastic rotor spins inside the distributor cap, firing each spark plug as it rotates. If the distributor gets faulty there the engine may not perform well. in most cases it has been noticed that only replacing the cap does not helps but with cap the rotors also need to be replaced. The procedure is as follows:--- 1) First of all disconnect the negative battery terminal. 2) Then remove the spark-plug wires . Note:-- Before removing the spark plug wires please note down how and where the wires are connected,then only remove the connections. 3) Then on the distributor there will be a cap.remove that cap.the cap is connected by two pins.you will have to press the pins from each side to loosen the distributor cap.Then lift the distributor cap from the top. 4)Then remove the rotor From distributor The rotor is fitted with two screws.Remove the screws and loosen the rotor. 5) Then lift the rotor out from its shaft. 6) To install new rotor and cap.reverse the procedure. This will help.Thanks.

How do I switch my points distributor to a hei distributor please help me :)


Easy. Set engine on TDC with distributor rotor pointing at #1 plug wire. Remove holdown bolt, disconnect small wires and remove cap and slowly lift distributor up paying attention to how the rotor moves as you lift. Note position of vacuum advance and make a mark on engine where rotor is pointing as you remove dizzy. On new distributor, rmove cap and turn rotor to match the mark you made from old rotor position. Install new unit with vacuum advance similar to the old one and rotor at correct position, and as you lower unit into place insure that rotor points same as old one did before you started removing it. The one other major issue is that a points style distributor has a supply wire with either a built in resistor, or a separate resistor inside the coil. The new unit needs full 12 volts to supply it so no resistor is used. If the old unit had a coil with internal resistor and your new unit has the coil in the cap, no change needs to be made. However if the old unit used an external resistor coil, you must now run a wire from the ignition switch "on" position directly to the distributor to supply full 12 volts. All of this depends on what you are working on so now don't you wish you had told us that?

Is it hard to change distributor on 2000 nissan pathfinder


Hi there;This is for a 2000 Nissan Truck Pathfinder 4WD 3.3L SFI 6cyl


Distributor Cap & Rotor - Removal & Installation


NOTE
The 1996-00 3.3L engines were equipped with a distributor.


Disconnect the negative battery cable.
If the distributor cap is to be replaced, mark the ignition wires for identification and remove them from the distributor cap.
Remove any components necessary to access the distributor cap.
Completely loosen the distributor cap mounting fasteners.
Carefully remove the distributor cap, taking care not to damage the cap seal or rotor, then position the cap aside.
If necessary, remove the rotor retainer.
Carefully lift the rotor off the distributor shaft.
NOTE
Inspect the distributor cap to housing seal for damage and/or cracks. Replace if cracks are detected.




To install:


Install the rotor onto the distributor shaft and tighten the rotor mounting fastener, if equipped.
Position the distributor cap seal on the distributor housing, then position the distributor cap on the housing.
Install the distributor cap by tightening the mounting fasteners in a crisscross pattern. Use care to not over-tighten the fasteners.
Reconnect the spark plug wires, making sure to install them exactly in the same position from which they were removed.
Reconnect the negative battery cable.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

My distributor cap fell off whiole driving, and truck quit. the rotor was also off, as both screws had fallen out that hold it on.. My son installed them about two years ago. Mabe screws were not tight in...


Hello,

I understand your problem, and I will try and give you the best advice here of what to do.

Yes, most likely when your son installed the distributor cap/rotor the screw might have been stripped some or just loose. And yes over a period of time they can work them self off, mostly because the rotor itself is the moving part. The distributor itself if screwed down correctly does not move, but the rotor inside of course does move.

The best way to solve this, and to make sure this works correctly, is to purchase a new distributor cap and rotor, reason for this is, then the screw will be new and do not have to worry about possible stripped where rotor tightens down. It is possible he might even cross threaded them, which is still better off to buy new rotor and cap (they normally come with the screw if not , have them match them up to fit) Just need to give like AUTO ZONE, the make, model, engine and they can hook you up. Now I realize you can use old cap and rotor, but problem is this, because it came off and so forth, why take the chance of the rotor or cap getting banged up, and then will could have some electrical issues, sense there plastic and only takes a small hairline crack to cause problem. best to replace both and then secure down snug. Almost any garage, or a friend that has a couple screw drivers and some knowledge can do this for you for like a cold beer. I hope this helps you, and I think this will be a easy, low cost solution. Thanks Mike from Fixya.

1985 Nissan 300zx seems to be "missing".


suspect 1) bad spark plug(s) - change whole set if needed, (2) failing ignition coil (3) failing
distributor component(s), or (4) worn out distributor cap and/or rotor - if these need to be changed,
change both the cap and rotor as a set.
COST: if yo do any of these repairs yourself, your parts costs would be fairly low, but getting a garage
to rebuild your distributor could be costly

How to remove distributor on a 1998 gmc pick up with 5.0 engine, do I have to mark anything or just take off bolt and pull out.


You need to mark in 2 places. With the cap off mark the position of the rotor button on the distributor housing first. Then you need to make a mark on the distributor housing that will line up with a mark on the engine itself.
When you put the distributor back in back the rotor button up before you put it in because the cam gear will turn it ahead as it seats. For example, if the rotor button is at 3 o'clock then back it up to 1 o;clock.
Don't force the distributor down at the end because you can damage the end that drives the oil pump. Fidle and wiggle it as you push and it should line up and drop onto the oil pump. Also DON'T turn the engine over while it's out or you will have to retime the engine. Hope this helps.

How to install cap and rotor on a 2000 chevy blazer 4.3ltre v-6


Disconnect the wires and take pictures with cell phone for reference to ensure you don't cross them when reinstalling the new distributor cap. Remove the two torque screws in the distributor cap and remove the distributor cap to access the rotor. Remove the rotor by lifting straight up and inspect the distributor for any condensation and corrosion. Clean the breather screen at the bottom of the distributor before installing the new rotor which just slides back in place. Install the new distributor cap and tighten the new torque screws, make sure you do not over torque the screws since the distributor housing is plastic and prone to stripping. Reattach the spark plug wires and start the engine and idle for 5 min and go for a test drive. Good luck and you may want to also buy spark plug boot lubricant to ensure the spark plug wires are fully installed when placed back on the new distributor cap and recheck connections after test drive. Keep me posted, be glad to know your blazer is running 100% and please rate.
