bad ground from the rear tail light

the green wire should be on a pulse wire from the distributor, not the coil

have you cleaned the battery cables?

also check the grounds for corrosion and continuity

What engine do you have? Let me know and we can go frome there.
Regards.

Check to make sure what trans you have. Someone could've changed the trans to something different, or maybe they are giving you a chevy starter when you need a BOP starter.

That is a good trans - damn near bullet proof, change the fluid and filter and replace it with B&M trick shift or ((Hurst Hot Shift fluid)) these fluids preserve the bands and gives firm shifts instead of the lazy slip into gears , you will notice a really big difference in the efficiency of the trans and nice shifts as well - only need to change whats in thew pan, also while you are under there check your linkage because sometimes it needs re adjusted (adjust on the thing that is a round cylindrical thing with a bolt on the side - your shift rod goes through this) have a partner get in ((after)) you loosen the bolt and have them put the needle on the dash centered on the (P) - retighten

Check for vacuum leaks at the intake and carb. base. Check your vacuum hoses and your brake booster hose. While running, spray WD-40 along the intake and see if the idle changes. Do the same with the carb. and visually check all your hoses for cracks or breaks.

look for a vacumn leak ??if not then put a litre of diesel into transmission and drive it around for an hour then drain and refill ,might not work but sometimes it does on older boxes with all this flash computer stuff on them

Choke coil & adjustment should be on side of carburetor.

Sounds like a faulty Throttle position sensor. Warranty should pay for parts & damage, talk to your dealer. The 88 -90 ford tempos had same problem & a driving school was using them, lots of kids & instructors got the heck scared out of them, but luckily no-one injured badly.

1 of 2 things Happened 1 Whoever worked on it Disconnected the "VACUUM HOSE" to the "VACUUM MODUELATOR" This Unit is Located at the Side of the Transmission about 2/3 way back Driver side I Believe -- if not Passenger Side. Has useualy a Steal Line that runs from BEHIND Carb Leading down to the trans. Vacuum Moduelator helps Control the Shiftpoints
and without it it will ONLY SHIFT MANUALY. Hoping this is Good Info for you and you get it Corrected Please DONT FORGET TO RATE ME thanx RejakWilson

Problem is the Turn Signal "FLASHER" unit, 1.Turn on Emergency FLASHERS 2. Go under Dash while they are on Listen -for Clicking sound then feel for it 3. Should Be a Silver Round Unit About as Big IN ROUND as Half dollar coin 4. ok now Look Around for the SAME EXACT Thing Clipped onto Something Under dash At Driver side Usually Between Steering wheel and Center HUMP in Floor, 5. once you find it Take OUT the first One you Found Emergency FLASHER) and 6. Put it In Place of Turn Signal Flasher, 7. Turn off Emergency Flashers- Turn Key in "ON" Position but don't start then Try Turn Signals. Yaaaa !!!! they work ?? LoL hopefully this Does the trick, if they work Buy new one and Replace Always Use NEW For TURN Signals as they are used Much More than Emergency Flashers. Hope this is Good Instructions For you and Helps you Solve The Problem, Please DONT Forget to RATE ME Thank you [email protected]

bad break calaper. replace both left and right, common problem.

Look in the clovecomopartment.

first you need to know what size the engine is in canada its metric , how many litre? in the u.s. its cubic inches. is the engine a 4cyl. , 6cyl. or 8cyl. most tune ups nowadays consist of sparkplugs and sparkplug wires , and like the other you need to know the size of the engine. its better to go to a oil change garage when they have a special deal on.

THEY CALL IT YHE WIPER TRANMISSION. THE LINKAGE THAT IS CONNECTED TO THE WIPER MOTOR FELL OFF BECAUSE THE NUT THAT KEEPS IT SECURED TO THE MOTOR LOOSENED & FELL OFF ALLOWING THE LINKAGE TO FALL OFF OF THE WIPER MOTOR.FIRST YOU HAVE TO GET A NEW NUT TO HOLD ON THE LINKAGE (IT MIGHT BE RIGHT UNDER THE WIPER MOTOR IF THERE WAS SOMEPLACE FOR IT TO FALL)REINSTALL THE LINKAGE, (IT ONLY FITS ONE WAY) PUT ON THE NEW NUT (TIGHTEN IT ENOUGH BUT MAKE SURE THE WIPERS CAN STILL ROTATE) AND YOU SET

Either your oil needs to be changed but most importantly The clearance in the connecting rod bearing have more clearance then tolerances allow. This could be due in part of low oil pressure. The gauge might show safe pressure but a manual gauge would give an accurate pressure. Hope this helps.
