engine stumbles
 

when i'm driving at low revs like under 2000rpm my engine is fine when i rev more it feels like the engine is struggling...in the morning my car wouldn't start so i changed the distributor. now i'm able to start the car but it doesn't seem to stop the stumbling prob. do u guyz think tat my fuel lines are clogged because i was having mileage probz b4 or could it be my O2 sensors.
any input from anyone would be appreciated.
thanx

you try changing your plugs?

yea the plugs have been done recently

its your head gasket, or the valves need adjusting. I have the EXACT same problem. if by any chance u find out what it is..TELL ME! but im almost 100% sure head gasket. check your compression if its all over the place..thats yer problem.

i dunno one more thing i'm guessing could've happened would be tat i gave my car to my friend for a day and he washed the engine bay.....i think tats why my distributor got messed up and i dunno tat can also effect the plugs if the water went in right?
the mechanic told me to change my plugs and the wires.... i'm gonna give tat a try to see if tat does any good.....if its something big i'm gonna throw out my motor its pissing me off its already got around 240k...LOL

head gasket. check if your motor shakes on idle. if it does...its pooched.

Do a compression check and see if one cylinder is way out of wack. What about wires? How recently was your fuel filter changed???

my wires do look bad btw how do u do the compression check?

need to buy the gauge and there's an article on T-I

how much is a new head gasket?

I doubt it's a headgasket. You'd know cuz your car would either be smoking and you'd be losing a lot of coolant.

Things to check:

Spark Plugs
Spark Plug Wires
Fuel Filter
is your clutch slipping?
are all your fluids top up?

Answer each of these questions, then we'd be able to help you more

after labour..a hell of alot! ONLY worry about that if your burning white smoke out the back. if you dont have plums of white smoke it might be fine. and for white GSR..a blown head gasket wont always burn coolant.

i tired changing my ignition wires it din help instead for some reason i'm getting back fires now and my fuel filter/pump and clutch was done 6 months ago
thanx for the input btw.....one more thing could it be the intake manifold gasket leaking or the ignition timing...thats all i could find in the repair manual....i was gonna get a gsr swap anyways i think nows the time

ever since i bought this car all i had was problems :headbang:

what about the spark plugs?

Next step is to do a compression test

Then put your timing back to stock specs. 14-18 degree's

hmmm i have no clue, bring it in somewhere.

i changed my plugs and used a new set of wires and now its fine but for some reason my plugs were really dark and its only been like a 1-2 months since i changed them. thanx for the help everyone

what kinda of plugs and wires are you using?

if your misfiring its the dizzy. erg..where do u live..I had the exact same problems..an fixed the misfire. Its electrical most likely. go to crappy tire. get a battery check done. if its good. then check your distributer cap n rotor for carbon. if its not clean metal..u found the problem. actually ----! ok! get some fuel injection cleaner. run it with your gas. get the penzoil or w.e!!! do that twice! and it'll be gone! hell shoulda thought of that..thats how i got rid of my misfire.

i'm in scarborough.....markham and sheppard....its a lot better than b4 i can't seem to figure out the firing order :confused:

And if you meant the order the distributor fires, it's 1-3-4-2.

i was looking for tat pic all over google lol couldn't find it. but thanx tat really helped

use that penzoil fuel injection cleaner!! :) I highly recommend it. worked great for my car.
