i have a 91 accord lx 4-door. its totally stock except for a cold air intake.

the problem with it is that when i take off, its really slow. it doesnt want to climp rpm's very well at all. but once it gets to 2500-3000+ rpm, it runs strong. it does this no matter the speed. if the rpms are low, it loses power. i have to keep it over 70mph to climp the bigger/longer hills on the highway, or downshift. now, when its running weak, it does not miss any. the check engine light is not on..ever. it idles fine too.

i have put new plugs and wires on it. new ignition contorl module. so, i dont know what the deal is. the exhaust is pretty rough...has leaks behind the cat (around the rear wheel area). i was thinking that the cat could be clogged. or maybe something with the egr or vacuum.

basically, i have some ideas that i can check in to. but i was wondering if this is a common problem, or if someone else has dealt with it and knows a definate fix.

i also have an oil leak from somewere...on the exhaust side of the engine. its getting pretty bad. are there any common problems that cause oil leaks that i could look into?

thanks for any help

 

90-93 accords, f22a engines, lag in power until 2500-3000 rpm. that's when they start entering thier power bands
[*]Max power:
[ul][*]F22A1: 125 hp (93 kW) @ 5200 rpm[*]F22A4: 130 hp (97 kW) @ 5200 rpm[*]F22A6: 140 hp (104 kW) @ 5600 rpm [/ul][*]Max torque:
[ul][*]F22A1: 137 ft·lbf (186 Nm) @ 4000 rpm[*]F22A4: 142 ft·lbf (193 Nm) @ 4000 rpm[*]F22A6: 142 ft·lbf (193 Nm) @ 4500 rpm[/ul]
as for the oil leak, you may need a new gasket for the oil pan.

 

thanks for the input.

i know the f22a's tend to lag somewhat on the bottom end of the tach (esp since its an automatic). but this is more than the normal lack-of-power lag.

i forgot to mention it earlier. but lets say you take off from a dead stop, on flat ground. when i give gas, it goes. but there is very little power. if you give it more gas, the engine sounds louder, but not like its winding up. it more like a loud bogging sound. its doesnt miss tho. so basically, you can barely give it gas or give it a lot, but it takes off the same...slow and with little power. actually, the more gas you give it, the less power it has... and the bogging sound gets louder. but once i get it up to around 3000rpm, it runs/sounds normal.

the oil is leaking from somewere higher on the engine than the oil pan gasket.

anyone have any other ideas?

 

have you check the coil, the samething happen to me i had the coil check and it was bad ireplaced it, the problem went away. also my car was not missing
