My turn for the ?????

[trishab@interwebb.com (Trisha Blethen)]

Ok, you all know, I don't ask many technical questions.....and so, this
is a little wierd for me....I'm not asking the huband is.....

Scenario:  sons' 86 4KQ........at 4800-5000 acts like it is on a rev
limiter.......we've been told to check the fuel relay -that it is the
wrong one......can't even find it.......any ideas? 

Next.....the boys want to get bigger- high performance type tires for
the street that will look good and fill the wheel well.....what do you
all recommend for size????????  Dealers are trying to sell us
195/60-14.....small damned things......

Thanks, 
Trish
