My 91 SE VG with 245K miles started skipping above 2500 rpm's.
It only does it when it's warmed up.I changed the cap,rotor and put on a new fuel filter....same.Then I jiggled allthe wire connections under the hood and made sure all vacuum lines were connected.........Now the car started idling at 1500 rpm's
Drove for a day and tried the wiring connections again.Now I have a missing cylinder,#1 actually........I gave up and took it to the dealer.
They had it for 3 hours friday and had not found the problem yet.

I thought it would be in and out.......Hell,I was giving them Ideas!

So.............any Ideas?

Fuel injector maybe?

Idea 1.: Get u car off-out from the shop.

- Start troubleshooting systematically by first describing symptoms in detail, (skipping is too broad). Figure out which may be come same source. Then list uself what has been done.

- The new problem, high idle, is possibly IACV hose leak; jiggle it again. Use liquid seal if u cannot get the hose tight.

- Replace ign wires with real wires; throw the soot hoses out.

- Do groundigs, start from distributor: http://www.cardomain.com/ride/748507/10

- Next, dont wiggle. Clean, add contact grease:

Thanks for the info.The car is supposedly now fixed.Something in the distributor was out of whack and they replaced the distributor....ouch!Anyway i would like to get a shop manual or Chiltons book,any one better than the others?

Did u get your supposedly bad distr back? ...possibly swapping corrected the mentioned grounding problem: install it back, and no problems.

Dont touch chiltons crap but in most desperate situation - and be directed to ditch...

Check my web page for manual -links.

I could have got the dist back but of course they wanted me to pay the core charge.The car runs great though.In the future I hope to do my own repairs but I was in a rush this time and It sure cost me!

cuda: If only one of the cylinders was skipping, that could not have been a distributor. Distributor is dumb - all it does is turning the rotor. It has no functionality to do something wrong on only one - if it's bad, it does it to all 6.

I made it a rule long ago: do not take the car to a shop before asking here. Saves me tons of money.
