Passanger side Miss fire while under heavy load

[ald872000]

Yo fellas,


Got another problem:

I was driving on the freeway pretty fast when I come to a sharp turn I ease off the throttle but when I come out of the turn I throttle again and hear the passenger side of the engine knock and begin to missfire. I ease of the throttle and the problem goes away.

Here's whats been done to the Vic: 1990 EFI w/MAF stock lopo
-new distributer/tfi module (times stock 10 degree tdc)
-new fuel filter
-new fuel pump
-fan clutch
(Did all these things before the knocking and missfiring started to happen)

Now what I feel is the tranny isn't shifting from 4th to 3th, I some what have to almost floor it to change when coming out of the turn and when doing so I begin to hear the knocking and miss firing.

Any Ideas on how to figure this one out?

Check the cap, rotor, plugs and wires?

yep, forgot to metion that but yea I checked and they appear normal and seem to work.

Could be one partially clogged injector making a cylinder run lean. Do any of the plugs look different on that side?
