have a 97 dc2 with 120k miles. bought it at 115k. is it possible for an engine to be sluggish after its all warmed up after like an hour of driving. i dont know if its just me but after like 3 minutes or warming the car up and driving it.. i can feel the pull but after like an hour or 2 of driving it.. acceleration seems slower and i can barely feel the vtec in the higher rpms. this is my second gsr and for sure this one is much slower. its all stock.
also i think my thermostat mite be stuck open or soemthing because it takes the car like 20 minutes to fully warm up.

all stock
lowered on neuspeed.
previous owner does not have paper work for any tune ups but claims his uncle changed the timing belt.

any input would be nice.

Change the t-belt if your uncertain lol

Does it just feel slow or is it actually doing something such as a misfire...

 

I've been noticing this on my car as well, and have been wondering the same thing.

 

i may be wrong so please dont hate :[

but ithink that its true, after a couple of hours of driving ithink the car does seem to slow down a bit somewhat because all the parts are hot and maybe the motor is "tired"?

at least your getting a turbo soon!

 

Well are you trying to say that after a long drive it may feel not as peppy as when you first start driving? Because obviously heat plays a key role in engine performance.

 

could be an oil pump issue.......and the radiator situation, usually you change the water pump at the same time you do the timing belt....so replace that to eliminate any problems....

 

Just replacing parts hoping to shotgun the problem doesnt solve anything and just wastes money Honda-tech needs to learn how to diag the correct way lol.

 

yeah i think it is a heat issue but my other gsr wasnt like this at all. even my cousin said that my previous gsr pulled harder STOCK.
eh this sucks.

PS i hate driving friends that weigh more than 200lbs on HOT SUMMER DAYS

 

Watch your coolent temp next time you go for a long drive. Although many are against it spacing your hood will help lower under hood temps and even keeps my coolant temp down With a stock GSR i wouldnt go to crazy though unless its really bothering you.

 

i think its all psychological because once you start driving your gonna push it more since you didnt drive for awhile, therefore thinking it is more power. But as you drive you start to loosing up and lay back. therefore, thinking it is slower than it actually is.

On a properly functioning cooling system, the under hood temps will have no bearing on coolant temps. If the radiator, fans, and waterpump are doing their jobs, the thermostat would be the sole determining factor of your coolant temps. If the thermostat is aftermarket, made to open at cooler temps than factory specs, then your coolant will be cooler. If the thermostat is stuck open, you will run constant cooler temps. If the thermostat is stuck closed, you will run constant warmer temps. So the people who said not to prop your hood would be correct in reference to coolant temps.

 

I understand the logic but ive seen it first hand the increased air flow and allowing the heat to escape from out beneath the seal of the hood made a noticeable difference. I owe the majority of that to the upgraded aluminum radiator but sitting at idle im sorry but that seal on the upper firewall traps a lot of heat in. Plus i phrased that wrong i meant spacing the hood to lower under hood temps hoping to increase the performance of the motor.
