i need help fast.
well i just finished my Dohc swap, and everything seems good. but when i driving it, it doesn't really "cruise" as long as im accelerating its fine but if i let off the gas then push the gas again it kinda hesitates for a second then sort of jerks/ kicks i guess you could call it. then it takes off really quick.
also if i have it just idling and i rev it say to 1500rpms it will rev up then go back down then kinda rev by itself a tiny bit, probably back up to 1200rpms.
if it matters, i did put a mopar performance cmputer in it, so i had to mix less then a half a tank od 87octane and filled it the rest the way up with 93 octane.
do you think it could be related to a vacuum leak or something, i rechecked all hoses several times and cant find anything.
or maybe another possibilty could be my throttle cable or something?
any help would be great. thanks.

i did the swap myself too. no problems however. but i would say it does sound like a vacuum leak. check for a leak around the tb because if you didn't get a new gasket that could be your prob. i had trouble sealing the tb goin from the plastic intake manifold on the sohc to the aluminum one on the dohc without gettin a new gasket. also check the iat sensor that coulda gone bad. any check engine lights? try usin the stock computer to finish up that tank of gas and maybe for one more tank and see if you throw a code. that is if you have a 97-99 stock dohc comp.

also the stock comp. will throw more codes than the mopar will. i eliminated my egr and evap purge solenoid system and the mopar comp for me never threw a code. but my stock one will throw an evap code a o2 sensor code and egr flow code very quickly and my mopar comp wont throw any of those. the only codes i've got out of the mopar comp is misfire codes and fan sensor relay

i have looked all over town for a new Tps sensor and cannot find the right one.
the one i need is where the harness plugs into the sensor horizontally. and it also has round plugs.
all the ones around here and the ones the plug in from the top and have flat plugs.
i have trade autozone, advanced, napa, car quest.
maybe the dealer?
any body know where to get it at?
