Hello again everyone! So, just got done cleaning out and tuning up my 1st gen and looks like things are going good, except for three things 1. Tach isn't working, how hard is it to pull the instrument cluster and if necessary, replace the tach cable? 2. Pulled the timing belt cover and inspected v-belts. Power steering belt was a little loose not a problem but there was a bit of oil crud behind the timing belt cover. Cleaned that all up but couldn't find the source of the leak, might be the crankshaft seal, how tough is that repair? 3. My MPG's are only about 16-22 tops. Hopefully this tune up will do the job but if not, what (outside normal tune-up stuff) could be causing this? I've replaced; air, fuel and blowback filters, cap, rotor, plugs and wires. Let the healing begin! Thanks!
