The '82 GL I'm trying to sell is making it very difficult. It's now hesitating, surging, jerking, on hard acceleration. With the A/C running, it just stalls out, dies. Last woman test driving it had to restart in the middle of an intersection - I wanted to die, or possibly beat the car to death.

ANYway, the very last thing I did to the car before it developed this problem was to use the Seafoam method to blow it out - as recommended on Turbobricks, where everybody says it does wonders and makes their cars faster and get better milage and makes their teeth whiter and shines their shoes with no side effects or damage whatsoever regardless of engine condition or age.

While it may NOT have been the Seafoam, logic tells me that if the only change I made between it accelerating like a rocket and trying to stall out on me was sucking Seafoam into the intake manifold, then that was probably the cause.

I suspect a PCV clog or throttle plate sticking. Could the Seafoam-fun have knocked loose some happily out-of-the-way gunk and clogged something like that?
And how do you GET to this stuff to clean it out anyway? B230F I dig, on this old B21 I am pretty lost.

BTW, The center vacuum nipple in the intake manifold has nothing attached, though that made no difference previously. I was told it should have a hose going to the flame trap? Also, my hands ain't tiny, how am I going to get to the flame trap (I believe it's buried under the manifold?)?

The previous owner has listed on his maintenance records stuff like "Emissions tuning - $70-gazillion dollars" which I assume to mean that somne goober-head mechanic pulled some vacuum hoses and screwed with timing and other ignorant things to make the car pass inspection, then charged the man a fortune for impairing the function of his car.

I don't know anymore, I was hoping to get about $600 for the car, which would cover all the money I've put into it, but even I wouldn't buy it running as it is. I don't want to work on it anymore (that's why I'm selling it) but I also hate to lose money on it when until recently it ran every bit as well as my '93 with 1/3 the miles. And probably has newer suspension components.

Grrr...
