Stoopid Hipster Posted February 27, 2010 Report Share Posted February 27, 2010 so i have installed my new tps and idle air controller on my 92' miata and am still having probs i was before a little better but not really the probs, 1. Idles roughly not very smooth kinda like a cammed v8 2.while reving at 5k gets really loud 3. once in gear at 5k it acts like its hitting the rev limiter (norm 7k) and wont go past it ...but its not constant some time a lil after 5k 4. all probs started after a injector fuse blew 5. with new parts every now and then it acts ok and will go all the way through 5k 6. while down reving like letting off the gas in neutral it sticks at about 2k for 30 to 40 sec then will drop lower. only engine mods are intake and spark plug wires other wise not sure all i can think of is idle speed maybe the tps sensor angle or or cam angle sensor (does the ignition timing.

zeitgeist57 Posted February 27, 2010 Report Share Posted February 27, 2010 I don't know a ton about Miata's, but it sounds almost ECM-related. Your title is a little misleading. Do you mean "put on new parts, but engine is still failing me" as opposed to "put on new parts that immediately failed" or "failed to solve the problem"? Sounds to me like you replaced some old sensors but definitely didn't find the culprit. What do the Miata boards tell you? Quote Link to comment Share on other sites More sharing options...
Stoopid Hipster Posted February 27, 2010 Author Report Share Posted February 27, 2010 miata boards still haven't said anything useful and i had probs and put new parts on that did nothing so the tittle became new parts still failing as in the engine is still falling Quote Link to comment Share on other sites More sharing options...

AJ Posted February 27, 2010 Report Share Posted February 27, 2010 fuel filter cloged, cat cloged, fuel volume (not pressure) too low, MAF dirty. Quote Link to comment Share on other sites More sharing options...
Stoopid Hipster Posted February 27, 2010 Author Report Share Posted February 27, 2010 it an "open door maf " so not dirty and its a new fuel filter you think a clogged cat would cause that? Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted February 27, 2010 Report Share Posted February 27, 2010 clogged cat, and poor fuel volume can cause it.. i forgot it has a flapper door maf Quote Link to comment Share on other sites More sharing options...
