shakey truck

im not very knowledged in trucks and i have '90 f150 lariat and the engine shakes alot when stopped or moving, and when i take my foot off the accelerator, it slows down quicker than normal - or when i barely touch the break, like it catches or something.

also when im stopping the truck shakes real bad, do i need to re-align my wheels, get the brakes checked out or what? thanks

Check the front brakes for the stopping, also I would have the transmission checked, and then the timing. How does it perform? any trouble with acceleration?

Have you checked the engine mounts to see if they are detiriated another thing to check could be the harmonic balencer

oh yeah the acceleration is kind of bad - when i accelerate after being stopped it takes a while for it to get up to speed, like its lagging or something

I would replace the spark plugs, but I would start at the front brakes, does it shake really bad at a stoplight? Or just when you first start it? By uour first post sounds like your timing chain could be going south or even a head gasket... Does it blow white smoke out the tail pipe all the time?


I don;t mean to alarm you with the possibiliies I'm thinking out loud.....

If they're old the can be burnt out to where they are chaning the timing causing a rough idle, I know this because when I bought my van in 2000 the plugs were burnt out to .060, they should only be .044
