WOW, my 240 is slow, help plz!

[StatixNWH]

I have a 93 coupe with a de. It has auto transmission. When i bought it it was slower than a E motor. I thought it was a fuel problem so i replaced everything in the fuel system except the lines...I also replaced the MAF. Hollowed out the cat, disconnected the EGR, and it was still slow. So then, i disconnected my knock sensor to put it back on base time, still slow. I hooked it back up becasue of an idol problem lol, still slow. What other suggestions do you have?

[StatixNWH]

i forgot to mention the symptoms part to half throttle it is fine anything more it starts to bog down and actuall slows down i can dry rev it in park or neutral and it wont rev high enough to even hit the rev limiter ive also set the timing on sevral occasions still slow i dont know how manny rpms it will turn because the tach doesnt work [cluster from an e] any help will be gratefull

I generally do but it sux you have to go up a hill to go down a hill Ialso changed out the ecu afew minits ago it is still the same old slow car

manual swap. auto motors are great once they are converted to manual. the cams are more agressive for some reason. my KA is feels unlike anyother 240 i have ever driven. pulls hard.

also u can remove ( if u wanna go faster)PowersteeringEGR completely ( and plug)Mech FanAc( its a clutch mechanizzzzem, but get rid of it anyway)

and have a boost ready empty engine bay like me

Its just the nature of the car my friend. It IS slow. haha just make sure you aren't running on 3 cylinders like I was when I first bought mine.

[StatixNWH]

do yall think it would have some thing to do with the transmission even though in park or nutral it still wont rev with out bogging down

i also have an89 parts car with an e it has my 5speed but i hear from some people that it wont bolt up to my de but i could have sworn the bottom ends were the same if not close idk

You know, my old 91 auto did something similar, I replaced all the ground wires from the battery to the engine with 2 gauge battery wire. Worked great afterwords.

well...today I found out it was out of cam alignment. I timed it and it seems to be running a whole lot better. The intake cam was off 1 tooth, and the exhaust cam was off 2. Now all i think i need to do for all power to be replinished, is to do the 5-speed swap. Thankyou for the replies.

**5-speed swap in progress**
