i just recently bought an 88 turbo 2 with a rebuilt motor but the idiots did not replace the fuel lines and one of them cracked and started a fire under the intake manifold burning the vacuum lines well i took it to a shop and had everything fixed and it runs fine now but after the car warms up to operating temprature it idles horribly and i wont take my car back to the shop because me and my friends have had more problems with this place then any other place ive ever took my car too so if anyone has any suggestions on what my idle problem could be i would greatly appreciate it

 

i just recently bought an 88 rx7 turbo and it came with a mazda remanufatured motor but the fuel lines on it were old and one of the cracked and caused a fire under the intake manifold melting a good portion of the vacuum lines well i had a rotory mechanic friend come over and help me and he did what he could but couldnt figure out everything so i took it to a shop and they fixed all my problem but ever since it has come back from the shop it idles like **** and niether me or the mechanic can figure it out and i dont really trust the shop to send it back to them so if someone could give me some suggestions on what they might thank it is i would greatly appreciate it

 

Nice car from the pic.

Well for idle you need to start hunting down and eliminating things.

TPS/BAC/Timing/Ignition-spark/Fuel/ Vacuum leak.....

It can be many things. Did they use new hose or reuse the old stuff? The old hoses can usually crack and leak because they are so brittle and hard.

 

it was replaced with all new hoses and all new fuel lines when it came from the shop and when i got it out and realized i had this problem i changed the plugs and the wires thinking it was that but that didnt really do much it doesnt really feel like a vacuum leak though im wondering if i burnt some wires or something of that sort

 

what do you mean by idles horribly. does it bounce? shake? not idle unless pedal is givin? give me a little more info. otherwise check all vaccuum lines, and it could be an intake leak.

all of the hoses were replaced with new hoses and so were the fuel lines too in a way when its sitting at idle it doesnt seems like its getting enough fuel like a might have burnt an injector wire or something
