Hi. thanks for any help youll be able to give. what happened was.

i was going down the highway and my check engine light started to flash 3 or 4 times i think. so i slowed down. and my problem now is that going over 55 it shakes like crazy and when i get over about 2 thousand rpm and going more than 20mph i hear a rattling noise. the check engine light didnt come on after that
its a 99 ram 1500 extended cam 318 v8 4x4.

Thanks again

 

Can you pull the codes from the PCM?

Does the engine seem okay when idling?

My guess is you have a transmission issue but without more info it is going to be tough to be sure.

 

Probably missing. Should get the codes read, and see what they have to say. Could be any number of reasons for a miss. Plenum bad, fouled plugs, bad fuel pressure, bad plug wires/cap/rotor.... etc.

Is it worse at about 45, when the TCC engages, and in fourth gear?

 

well the faster it goes the worse the shaking is. and the noise i only hear at about 2200 rpm. and it seems fine when idling
thanks

 

could be clogged cat for the rattling noise. as for the shaking i dont know. could be front u joints going bad and shaking so bad that it is messing with the wheel speed sensor if you have them.

 

My guess is clogged cat, and for the miss, wires, cap, plugs, plenum, hmm

 

yeah. i remember we replaced the cat once. HOPEFULLY tis not a trans issue
thanks for all the help guys

 

Flashing cel is severe misfire, the shaking can be from a misfire thats bad enough, but your cel should have stayed on for that.
You really should pull the codes, then come back and post them. Not sure if your in the US or Canada, Mexico, or across the big blue, but, find a place that will plug in your truck and find out what codes are stored.
