Need Help with my 94' Accord EX...acceleration/power an... - 4/28/2008 7:39:25 PM    ford   Posts: 265 Joined: 4/28/2008 Status: offline HI! first of all i have a 94' accord EX (I4-Vtec). it has 150k miles on it. im not really that mechanically inclined person. i mean, i know some stuffs about cars but im not really like those mechanic persons...who knows a lot about fixing cars and stuffs... 1:) My first problem is this: when i accelerate, it feels like the I4-vtec engine doesnt have the torque/power to really accelerate fast. and that is already in first gear. i dunno why is that.. im guessing it has something to do with my exhaust system...cuz my exhaust system is still the original exhaust(pipes,etc.) and it does have little bit of holes on it... 2:) My second problem is that: when im already cruising, when im stepping on the gas so that the car will just maintain its speed, it fluctuates...im guessing it has something to do with the fuel filter..i wouldnt want to say the spark plugs cuz the plugs r new...so.... Please Help Me With My Car's Problems..... Thanks In Advance ... Post #: 1

If it's a manual, a worn clutch would fit #2 in a long stretch... _____________________________ USE ME TO SEARCH HAF PWOTY 2008! (in reply to JimBlake) Post #: 3

Look in the DIY forum, I think there's some instructions about how to jumper the SCS connector & read the error codes by watching the check-engine lamp & the D4 lamp flashing.  Knowing what errors are being reported is important. Auto tranny has a cable from the throttle to help the tranny decide when to shift.  Adjusted wrong, that might cause the tranny to hunt back & forth between gears. Your #2 could mean a couple different things... - You hold a perfectly constant position of the gas pedal & the car surges as if you were pressing & lifting your foot. - The engine RPM rises & falls as if the tranny were slipping, then not, then slipping. - The tachometer bounces but there's no indication (rpm by sound, or surging of the car) that the engine is actually doing that. Which is it??  (or describe it best you can) _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to ford) Post #: 5
