I have a 1989 Geo Spectrum with 1.3 engine. There's a copper pipe beside carburetor extremely hot! Near by 2 wires connecting to a 12 volt that's on top of motor. There's a hose off It coming from Erg valve. Seems like there's something been removed. Whenever I rig it with 2 soda cans it runs great but as soon as the alumni cans blow apart after couple days it starts missing horrible and gets very loud. Last nite i was when finally getting stranded The accelerator idle up on it's on I just knew it was gonna blow up! It didn't have any power at all matter of fact i thought it jumped time! Can anyone help me find what the name is and a diagram of motor?

You will need to have a service manual.
Basically what you need to do is make sure the number one cylinder is at top dead center on the compression stroke and the valves for the number one cylinder are both closed. You will need to have the timing sprocket at the cam shaft exposed. It will have timing marks which need to be aligned. This is where the manual will come in handy.

Be very careful in moving the crankshaft with the timing belt removed or mis-adjusted. Very very very few engines have clearance between the valves and pistons. If you use the starter to move the crankshaft with the timing sufficiently off, you will bend / break either a valve or piston.

Best of luck, Jim

What interchanges with 1989 geo spectrum

This depends on which part. Salvage yards have sets of books called Hollander Interchange Manuals that cost big bucks, but give all the info you seek. See if you can find a friend with access to a set, or beg info on individual parts from a salvage yard that might just have what you need.

Where is the grounding strap located on a 2000 Jeep Grand Cherokee?

There are grounding straps everywhere on cars and trucks. Begin by looking at the battery. The posts have cables coming from the (+) and (-) terminals. The (+) side has a cable that goes to the starter, solenoid and fuse box. This cable - and the wires connected to it - are insulated and never touches the vehicle frame, body or exposed metal. The (-) cable however is securely fastened to the engine - usually near the starter or other convenient, easy to access location. Additionally, there are copper jumpers or straps that extend from the (-) post to the exposed metal portions of vehicle frame, body panels, dashboard, etc. This provides a path for the (-)12 volts and ensures it is available everywhere on the vehicle with out the need to run a separate (1) wire to each location that has a (+) wire.

Copper is used as it is a better conductor and more flexible than steel. You should be able to connect one lead from a 12 volt test light to the (+) 12 volt battery post and the touch the other lead anywhere on the car that is metal and light the lamp. If the lamp fails to light or lights only dimly - it because the metal isn't connected to the (-) 12 volt side of the battery due to a missing ground strap or because of a poor or rusty steel connection. Placing one or more straps between metal that provides a bright test light and the metal section that provides a dim or no light at all will make the light glow brightly.

89 Geo Spectrum. Was at the autoparts store had them hook up diagnostic to test battery, starter and alternator. Everything tested ok. However when I left my car seemed to be running unusally high/fast. I...

you seem to be snatching at straws. that is ok. many do.
panic sets in.... its a machine and all fail.
You have dangerous high idle speeds, this is dangerous.
why not seek help. any mech can find this, Any!

The car has EFI , and idle controls.
A/Cs sets faster idle , by about 200 rpm ,
800 hot , to 1000 hot (in general)
The car has an idle speed controller that is failing.
there are other ways for this to happen, all complex.
1: intake manifold air leaks.
2: some dork, spun the distributor guessing at timing, fire him.
3: ISC bad. (or IAC) electric idle or thermo idle controls
4: throttle linkage jammed. (cruise, throttle or A/T kickdown)
5: or Toyota disease, the floor mats are hitting the throttle (dumb)
there are more..
it takes tools to fix cars, and know how. do you have tools?
that includes gauges.
guessing is expensive.
ask any mechanic to look, its not costly for just a look.

To avoid confusion, remove and tag the wires one at a time, for replacement.
