Chevy Corvette

My 1984 corvette transmission is not shifting into overdrive. It shifts first thru third fine.

You have an air vacuum type leak around the intake manifold area , computer will continue to compensate the 14 parts air to 1 part fuel each time which makes it chase the problem back and forth.

You can try WD40 spray that can help find the leak and not hurt the distributor or elec. Tighten up all bolts you can find on top of motor , to see if any loose. If you find leak just use some silicon. Could also just be a small vacuum hose came off somewhere.

Ensure the headlamp switch is in the OFF position.

Remove the upper garnish molding at the headliner.

Remove the right and left side rear window garnish molding.

Lower the rear of the headliner in order to access the electrical connector.

Disconnect the electrical connector.

Attach a short piece of wire to the high mounted stop lamp connector in order to assist the guiding of the harness through the body.

Remove the high mounted stop lamp screws.

Remove the high mounted stop lamp from the vehicle.

Right above the oil filter , in the engine block.

if you have a 4 cyl timing sets at 11 to 13 degrees and firing oder is 1-3-4-2 if you have a v6 timing sets at 9 to 11 degrees and firing order is 1-2-3-4-5-6- 4cyl front of engine 1234 v6 front left 135 front right 246

It could be a number of things, in addition to those already mentioned. In regard to the carburator, it would more likely be the power valve in lieu of the accelerator pump. It could be a burned valve. (do a compression test, and a leak-down test on each cylinder to determine the condition of the valve train) It could be a collapsed lifter, or a broken valve spring as well. Also, depending on the care of the engine as well as the milage, it could also be a flat cam lobe. Is it back firing through the carburator, or through the exhaust?

make sure the ignition timing it correct, the accelerator pump in the carburetor could be bad

possibly a loose connection to a sparkplug that is causing misfiring

You have to remove the plastic access panel located in the cargo area first...then, remove the three 8mm hex head nuts from the studs. Careful as these can seize over time and you end up twisting out the stud....use some penetrating fluid on them first. They are a little hard to see but if you get in with a flashlight you can see/feel around for them. One of them is accessible through the access hole on the inside edge of the access panel, through the body itself. The other two are on the top and bottom of the housing. If they come out without twisting off, put some anti-seize on them. You CAN remove the bulbs themselves without taking out the light assembly, with a half turn counterclockwise, but they can be a pain to twist out if your fender wells are rusted, as they get clogged with mud/road grime.

1968-1982 Corvette heater cores typically begin leaking due to a breakdown in materials dropping anti-freeze and coolant on your Corvette's carpet. This is not a pretty sight. Removal of the heater core takes place from inside your Corvette. First the RH side lower dash pad must be removed, then access can be gained to the inner heater box. Remove all ductwork (windshield defrost, floor duct, side ducts, etc.). The main inner heater box is supported to the firewall by 4 to 6 studs, these stud plates are riveted to the inner heater box. By removing the nut on the opposite side of the firewall the inner box can be removed from the Corvette. The heater core is mounted with straps inside the inner heater box. Once the inner box is removed from the Corvette, the heater core can be replaced and reassembly can begin. At this time it is also a good idea to replace all the seals in your Corvette's heater & air condition system. Seal kits for 68-77 & 78-82 Corvettes include ductwork seals, inner box seals, heater/ac flapper door seals and firewall mount seals for internal and external heater boxes. Replacing these seals not only improves your Corvette's heater & AC performance, but also eliminates air drafts which are common on all C3 Corvettes.

Try changing spark plugs and wires

It is the VAT system, thinking your are a car thief. Repair or replace the system.

Open the rear doors and secure them so you don't get hit by them while you do this. Look in the sheet metal directly behind the tail light assembly you wish to fix. There should be two rubber plugs; if so, remove them to gain access to the bolts that hold the tail light assembly. I would recommend a magnetic tool, as these bolts can slip and fall into the crevices back there! Rotate the assembly away from the body. If you try to pry the unit off, you will break the mounting tabs located in the forward portion of the tail light assembly. This means you have to grasp the inside part of the assembly that is closest to the middle of the 'burban and rotate them forward towards the front of the vehicle. For example, the rear passenger side tail light assembly would be rotated out in a counterclockwise motion towards the fromt of the vehicle. Unscrew the light bulb holder assembly and remove the bad bulb. Replace it with an exact replacement, and use the dielectric grease! It keeps out the water and prevents the corrosion of the bulb contacts. Hope this helps!

the paint code on an 85 corvette is located on the underside of the compartment door behind the drivers seat it will be the code on the bottom of the label after it says bse/clr coat it will have a lower marked by L and an upper marked by U followed by the four digit paint code

i need a vacuum line diagram for a dodge 1500 4x4 automatic transmission, where does the large vacuum line coming off the top of the transmission hook up to The large hose coming off of the top of the tranny is only a vent hose, it is hooked to a braket that is bolted to the top of the bellhousing, trust me I am a professional

Counter clockwise to advance.......clockwise to retard

Figure around 8 seconds 0-60, 15-16 seconds in the 1/4 mile and around 120-125 MPH top speed (for the record, a current 4 cyl Toyota Camry can easily beat those figures...)

That would be a 5.7 liter (350 cubic inches) engine, V8 meaning it has 8 cylinders in a V, 4 on each side,& TPI (Tuned port injection) is the type of fuel injection system on the engine, OHV (over head valve)

1953

It is screewed into the drivers side head beside the first spark plug in the front.

no, the hinges are different and size

Assuming you are asking about the Targa top, you use the special torx tool to unscrew the four bolts. There are brackets in the back of the car so that you can store the top. It goes in rear edge first.

Break it with a hammer!

to make sure the temperature of the fluid in the radiator is cool enough

Yes the word corvette is a noun. The plural is corvettes.
