When im in low rpms, i start to accelerate slowly and it seems like it studders. but i can raise them and it wont do it. i hope this is enough for someone to help. No check engine light also.

thanks

I got the same prob right now.

Was driving fine and parked it for a like 2-3 hours and then when i started the car and let it warm up a bit. It shudders when driving on the lower rpm espically when from a stop, and the exhaust sounds a little louder. Not to mention that the it lopes like hell and it's stock cam.

I thought it would be one of the plug wires that is a little close to the exhaust, but after careful examination it wasn't that. So i'm clue less right now.

 

right, i can drive fast and nothing happens, but when i down to low is when its awful, whos knows

 

check it out bro. i had the exact same problem after i put headers on my car. what had happened was, while putting the headers in i accidentally hit one of the plugs with the header. it made a hair line crack in the #1 plug. after everything got buttoned up i took it for a drive and noticed that it would stutter in low rpms and also when the skip shift kicked in. i thought it was either a fuel delivery problem or an ignition problem. fuel pressure checked fine, so i started to rip in to the ignition system. replaced coil, ICM, and opti. nothing problem got a little better but it was still there. so i looked under the hood one night to see if i could see the fireworks. and what do you know, i had some really bad arching on # 1 spark plug. it had a hair line fracture from the header install. so you might want to check plug and wire. i had the same problem you had. good luck hope this works.

 

first check plug wires, plug condition?, coil wire and coil condition, if all are ok , fuel filter under car, if all still the same then it could be the optispark starting to go out.

my car did just what you described and it was the good old optispark.

replaced with the dynaspark, expensive but car runs great and miss free

 

thanks for the good info guys.

Now, i did change my headers, and i very well could have bumped a wire. I changed the plugs and wires about 5 months ago, so i know they arent going bad. But im fearing the opti, i dont know how to change that, but i will figure it out.

Fuel fliter has been changed.

i guess tonight i will check for the firework show.

how much was that dynaspark?

 

it was 610 including shipping.

it is very high but quality is the very best out there and i plan on never selling this car, i bought it brand new in april of 94.

they will rebuilt it for about 38 dollars as long as their seal is not broken regardless of miles.

 

where did you order it from?

 

check out http://www.dynotech-eng.com

that site should tell you all you want to know

 

thank you for the help.

 

i found this company as a result of this board, so just passing the info along - tha is what it's all about

 

right on man.

 

well i looked at it a little more and the whole tranny shakes also, and it kinda does sound like its not idleing smoothly.

 

Check your MAP sensor. Also you could have a rip in your intake elbow. Check the plugs and wires to see if they are touching the headers or if a wire is lose. Trust me, check all the simple CHEAP things. I thought my opti was going, but it turned out to be bad msd wires.
