- Is this a carb of fuel injection engine? I have the smae problem on my '82
- and I am pretty sure it is the TPS (throttle position sensor) - We had it
- hooked up on my friends computer, and that was the only thing out of wack.
- According to the manual, it is non-adjustable, only replacable.

- The gear has nylon coated teeth, and the nylon has a tendancy to break off
- after 60K or so miles, making it hard starting, rough idling, poor acceleration,
- etc.

- Very easy, when you take the engine out of the car :-)
- Actually, its not too bad. You have to take off the passenger side wheel and
- there is a plastic splash guard that comes off the inner fender well which
- gives you limited access to the crankshaft pulley, and some of the timing
- cover bolts. The oil pump is attached to the cover also, that has to come
- off, so does the alternator, power steering pump, water pump, the AC compressor
- bracket may be in the way, etc.
- If you do this in the car, without air tools, I would plan on 1 long day,
- (maybe 2 days), depending on your level of skill and tools you have.
- I would also recommend replacing the water pump and the oil pump while you
- have them off - the oil pump is in an aluminum housing, and it tends to wear,
- and the water pump just on general principal - It will usually break 30 days
- after you have it off (Murphy's law).

-
- Never did one - I can look at the shop manual & check if you want - email me
- and let me know.
- It's probably riveted in, if it is the original, so you would have to
- grind the rivets off, and borrow or rent a BJ splitter - usually they are a
- 1/2 hour job (again, with the proper tools)
-
- > Any other suggestions about making this car behave normally are welcome.
-
- I am still trying to find that out myself :-) I did have a suggestion to
- replace the distributor with a non-computer controlled one and chuck the
- computer - sounds like a good idea so far.
