Hi folks,
I'm excited to say that I'm now an owner of an SPG! Yep, since Friday, when I bought it for $600 and drove it home! Carefully, since it needed a clutch master cylinder. But I put in a new master cyl. over the weekend and it shifts fine now!
The previous owner, a used car dealer, had put in a new clutch slave to try and correct clutch letting out at the floor and gear-grinding.
Now, I must say it's my first experience driving a Turbo, and I always have a BIG GRIN on my face whenever I push the go pedal and that boost comes on!
This SPG is an '87 model, and is also my first experience with LH 2.2 injection (my '84S is CIS and Mom's '90 and my non-roadworthy '89S are LH 2.4).
With that in mind (me being new to both Turbos and LH 2.2), I've got a few questions:
1) What position is base boost on the dash guage? I know this is the default setting the system reverts back to if APC system malfunctions, I just don't know what I should be looking for in terms where this is on the guage.
2) There is a broken spade lug terminal attached to a dangling wire near the throttle body. I'm thinking the terminal was attached to the driver's side throttle switch (not the TPS on the passenger's side of the throttle body which the LH system uses). The wire is black and has a black plastic shroud on it's terminal. What is this driver's side throttle switch, by the way??? Is it for A/C?
3) I am having trouble telling whether or not the APC solenoid valve is chattering, if this engine is spark knocking, or both. I know what spark knocking sounds like in the 8V 900 because my '84S will do that on most every hill unless I used premium gas--even w/timing correct on the 8V. (NOTE: I filled up the SPG this morning with 12 gallons of premium 93 octane fuel. However, that means the previous owner's 4 gallons of fuel was in the tank, and it may have been regular gas, not the required premium gas! I doubt the p.o. bothered to notice the "premium fuel only sticker." The owner's manual says that on the 900 with SPG option, premium fuel is recommended and performance will be less than that of a standard Turbo model if premium is not used.)
4) I installed some NGK BCP6EV spark plugs (gold palladium electrode) in this SPG over the weekend. The P.O. had stuck some Autolite plugs in there, so I put in these NGK's which I was intending to use in my '89 900S project car. The Bentley 16V book says these plugs can be used in the Turbo 16V models for "city driving." I do some of my driving in the city but I will (hopefully) be doing some backroads mountain driving, too, on the weekends. Any comment? Would the BCP7EV be better?
5) I heard a tapping noise from the valve cover area during idling after warmup. If I rev the engine slightly (say, to 1800 or 2000 RPM and above), the noise goes away. Bad hydaulic valve lifter? Valve timing chain loose?
I don't want to overload y'all with too many questions at first. I've still got to check timing, change the fluids (convert to M-Benz coolant), put in new thermostat (82°C) and thermoswitch, delete the radiator fan time-delay relay per Townsend method, fix the reverse lock-out pin on the shifter, trace down a rattle in the right rear wheel area, try to do something with the original non-working SAAB/Clarion radio, etc.
But for $600, I couldn't go wrong!
Thanks in advance,
Micah in NC
