    Car is slow and slugish after engine change

    So if you haven't been reading the forum, i have had some problems.

    The car was wrecked, then repaired. Then the engine went out.. And we got a new engine in the car.. And by new i mean used.

    So now that we have the car back, it feels completly like a different animal. Real slugish. I have to keep downshifting from all the gears just to get up hills that would normally never struggle.

    And in the bottom of the rpm rage its clunky, like i shift to 1st and there is a CLUNK sometimes if i release the clutch to shift. I have to keep the rpms high all the time.

    Now if i shift to one, it seems to take a second or two to spool up the strength to do anything. Same thing for 2nd. Once it gets into 3rd and up it seems better because im moving faster generally.

    But it definatly seems to be a lower rpm problem.

    Does this seem familiar to anyone?

              Exactly what I was thinking.

              Is the car smoking at all? How many miles are on the used engine? Is it an F22a1, F22a4, F22a6? There are numerous questions that need answering before we can really help you out.

                Well, this is the deal. My father had his mechanic do the work. I asked him all the info before and he didnt know. All that he mentioned is that the mechanic "assured" him it was a good engine. My dad is a little green if you ask me. But then again, im not sure if i would hang on to the car after the accident.. then the new engine. Im hoping that there a compression test done and all, but i don't know anything about that. I would have prefered to get the engine rebuilt, at least that could be a little consistent.

                Im not sure about all those numbers.. il try to find out. I dont know what engine. its from a 1991 honda accord LX.

                  No, its not burning oil or anything. Doesnt smoke and seems from the outside like a perfect car. But driving it means something entirely different.

                    Well, if it is from an LX then it's most likely an F22a4. What model do you have, DX, LX, EX, SE? The EX and SE have the F22a6 which make 20hp more than the other lower models and also has IABs etc. There are many differences to look into. Maybe you have an engine with less power, 20hp would be noticeable.

                      I have the LX. So i think i have about 130 hp. It sounds more like i got 50 hp now.

                      Could it be that its from a EX and somehow got messed up in the install. I really wish i knew more info on this engine. I have only gotten the car back a few days ago.. a few weeks. But i drove it for 4 days straight. no long trips. Took it on the highway, and it just seemed to need more power. I never had to downshift before to 3rd on the highway for little hills.

                      I hope i get the car fixed. I got my motorcycle down this week so i need to drive the car.

                        The EX would give you more power. Well, maybe, I don't know how it would operate with the LX ECU. I'd pull the spark plugs and inspect them. Spark plugs can tell you a lot about how your engine is running. Then you'll probably narrow it down to a sensor problem. I'm just speculating.

                          Does anyone think there could be a possible vacuum leak or maybe the timing might be off? Those are two things that can make your car sluggish. As for the clunking noise I just don't know. I would assume something with your clutch maybe?
