Hello everyone im new to the forum and would greatly appreciate it if some can help me solve a prolem So ive had my 03 mazda p5 for about 3 months, and now it does this thing when i drive in the freeway at a constant speed for about an hour or so it accelerates like its strugling and wont let me speed up wont let me pass 4000 rpm for about 20 seconds then it goes back to normal and accelerates normal and then i can actually speed up . It comes and gooes so i have to stop and wait for it to cool down after that i can start driving But it will keep doing it. It seems the problem happens after 45-60 mins of driving so i think i has to be either a censor or throttle body iacv, map, etc Im going to replace the coils and spark plug wires next, ive already changed the oil, spark plus, and coil boots. can some one please HELP before i sell it and buy a civic
