Hi all,

 

Drove my 82 still EFI to show and shine day at a

hot rod, custom and American car day, going all ok!!

 

Coming home hit the gas pedal (wot) car faltered,

trans kicked down but that is about all that happened,

backed off the throttle trans changed back up converter

locked up car accelerated ok with this partial throttle

opening.

 

Misfire under load is then the best description i can give.

 

Drive car home using light throttle only, struggled up hills etc.

 

Long day, up early also i have two young kids (6 months and 3yrs,

read tired) so i couldn't be bothered to look to deeply today,

besides popping the hood and pushing the throttle assembly

by hand to eliminate the throttle linkage from the equation,

engine revs up to maybe 2000RPM (hard to say without putting

a tacho on it) and just stays there (goes flat).

 

My train of thought which is a bit ragged at the moment points

me towards crud in spray bar assembly (plug wires #5 and #7

are separated).

 

Did i mention that i had recently changed the timing chain,

inlet manifold gaskets, cleaned out throttle body and

changed the valve stem seals? The car has been running

OK for the last week since the major surgery and the car

has never idled so well (even now with the misfire).

 

Will have a look tomorrow any other chain of thought will

help my overstretched mind.

 

Thanks Neil Thorpe underpowered black 82 imp.
