This may be related to one of my previous threads "Black spark plugs - one side only". I think that the fuel to air mix was way off- unburnt, or not enough, fuel, and that caused my weird burn pattern.
I discovered that the fuel/air mix screw is exposed on my 22R (carbed) - there's no cap on it - (previous owner tinkering I reckon) so, with some work on that screw, the engine idle and the fast idle for weeks, I believe my truck is idling as it should, there's better combustion, and no hesitation during a cold acceleration.
I also think that the timing may be off and the valves need checking -- I have what I think is a valve lash-type sound. It appears on downshift in 2nd gear or at a certain RPM (but the sound seems to lessen when the engine reaches operating temp. or I add an octane booster in the gas tank). So I thought carb/engine.
I was thinking that a clutch component was malfunctioning (since the annoying downshift sound is like a J-brake), but I just dunno.
Here's my plan (and any input is valuable - I'm trying to learn and save money. Oil changes, air filters, carb maintenance, window regulators, filters, various fluids and interior work surmises my 22R expertise at the moment I'm afraid. I'm not a mechanic.
1) I would like to replace the whole
ignition system with all stock/NGK parts - just like when it rolled of the factory floor in 1987.
I'm requesting assistance in finding a reliable, honest and reasonably-priced resource for OEM 22R carbed ignition parts - everything else but the plugs. Can anyone recommend a company?
I'm in the land of the $95 OEM windshield wiper arm at the local Toyota parts place, so I don't even want to ask how much the components will be there!
2) I would like my timing, fuel/air mix, fast idle and regular idle reset to stock (or whatever settings needed to eliminate hesitation and valve lash). I think I'll wearily let the mechanic take care of that. I've seen different specs on these and I don't have a timing gun. And the idle 'specs' on the web seem to be truck specific; I followed the 22R carb guy's instructions on his website, but it made the valve lash worse.
3) I want the valves checked (if the shops do that without mandating a valve job).
I'm asking if any fellow Toyota lovers can estimate what kind of cost I'm looking at for i) valve check ii)valve adjustment; or if I need either.
4) In a previous post, I asked about my temp gague not functioning properly (it moves, but only to a cool 7 o'clock position which I'm sure is incorrect). I'm aware this could be the temp. sender or the thermostat - while the truck's in the shop, I'm gonna have that fixed too.
I'm asking how difficult this is for a mechanic to do; and whether to expect a huge bill cos they took 2 hrs to get at the sender, for example.
I agree that this is kind of a strange post; and, yes, I have Googled all these issues. Flashy websites with free shipping can be misleading, and may not be the right choice for my needs.
I would like the stock parts, stock adjustments and a good price for this ignition overhaul; and I know that at least one
fellow Toyota owner must have done this and can provide tips i.e., perhaps my idea of using all NGK components isn't the best way to go -- perhaps I would benefit from a different coil than NGK or MSD wires. I just don't know.
I've been dial-up
surfing for an ignition kit, NGK's site, Denso's site etc. for four days now!
If some kind 22R-lovin' member can at least start me off in the right direction on any of the above issues - idle speeds, air to fuel mix, timing, radiator gague malfunction I'd be forever grateful.
The bottom line: the current distributor (Bosch), the current wires and coil(?) need changing and the valve lash must disappear.
I love my '87 and have poured at least four times the purchase price into restoring it.
Again, many thanks in advance.
