IowaPathfinder Posted April 7, 2004 Share Posted April 7, 2004 When accelerating from a stop with the pedal set in the same position the vehicle seems accelarates but it's not smooth. From 1000rpm to 1500rpm fine from 1500rpm to 2500rpm it seems to yo yo. It doesn't die or sputter. Its still smooth it just seems to be a loss of power. When it hits about 3000rpm though it takes off like the bat out of hell it always has and is smooth all the way through 5500rpm. Fuel pump or timing belt is my guess with leaning toward the fuel pump since it's not consistent. 1997 SE 126,000+ Bought with 68,000 2 1/2 years ago. Replaced fuel filter, plugs, brakes, struts, diff service(fr,r,tc), new tranny filter and fluid, A-arms. I am a stickler for maintence so I am all over it normally. Any ideas or past experience would be great. Link to comment Share on other sites More sharing options...
mikesmaximase Posted April 8, 2004 Share Posted April 8, 2004 Check your cap and rotor and maybe the plug wires. I dont know if you did all them when you did the plugs or not but an easy check. Link to comment Share on other sites More sharing options...
